Angkor Wat combines two basic plans of Khmer temple architecture: the temple mountain and the later galleried temple, based on early South Indian Hindu architecture, with key features such as the Jagati. It is designed to represent Mount Meru, home of the devas in Hindu mythology: within a moat and an outer wall 3.6 kilometres (2.2 mi) long are three rectangular galleries, each raised above the next. At the centre of the temple stands a quincunx of towers. Unlike most Angkorian temples, Angkor Wat is oriented to the west; scholars are divided as to the significance of this. The temple is admired for the grandeur and harmony of the architecture, its extensive bas-reliefs and for the numerous devatas (guardian spirits) adorning its walls.
The modern name, Angkor Wat, means "City Temple"; Angkor is a vernacular form of the word nokor which comes from the Sanskrit or Tamil word nagara meaning capital or city. wat is the Khmer word for temple. Prior to this time the temple was known as Preah Pisnulok, after the posthumous title of its founder, Suryavarman II.
Angkor Wat lies 5.5 km north of the modern town of Siem Reap, and a short distance south and slightly east of the previous capital, which was centred on the Baphuon. It is in an area of Cambodia where there is an important group of ancient structures. It is the southernmost of Angkor's main sites.
The initial design and construction of the temple took place in the first half of the 12th century, during the reign of Suryavarman II (ruled 1113 – c. 1150). Dedicated to Vishnu, it was built as the king's state temple and capital city. As neither the foundation stela nor any contemporary inscriptions referring to the temple have been found, its original name is unknown, but it may have been known as Vrah Vishnulok after the presiding deity. Work seems to have ended shortly after the king's death, leaving some of the bas-relief decoration unfinished. In 1177, approximately 27 years after the death of Suryavarman II, Angkor was sacked by the Chams, the traditional enemies of the Khmer. Thereafter the empire was restored by a new king, Jayavarman VII, who established a new capital and state temple (Angkor Thom and the Bayon respectively) a few kilometres to the north.
In the late 13th century, King Jayavarman VIII, who was Hindu, was deposed by his son in law, Srindravarman. Srindravarman had spent the previous 10 years in Sri Lanka becoming ordained as a Buddhist monk. Hence, the new King decided to convert the official religion of the empire from Hindu to Buddhist. Since Buddha was born and died a Hindu and since divisions between both the faiths appeared seamless, citizens were quick to follow a faith founded on tranquility without a need for material gain and power. This made the conversion relatively easy.  Hence, Angkor Wat was converted from Hindu to Theravada Buddhist use, which continues to the present day. Angkor Wat is unusual among the Angkor temples in that although it was somewhat neglected after the 16th century it was never completely abandoned, its preservation being due in part to the fact that its moat also provided some protection from encroachment by the jungle.
One of the first Western visitors to the temple was Antonio da Magdalena, a Portuguese monk who visited in 1586 and said that it "is of such extraordinary construction that it is not possible to describe it with a pen, particularly since it is like no other building in the world. It has towers and decoration and all the refinements which the human genius can conceive of". However, the temple was popularised in the West only in the mid-19th century on the publication of Henri Mouhot's travel notes. The French explorer wrote of it:
"One of these temples—a rival to that of Solomon, and erected by some ancient Michelangelo—might take an honourable place beside our most beautiful buildings. It is grander than anything left to us by Greece or Rome, and presents a sad contrast to the state of barbarism in which the nation is now plunged."
Mouhot, like other early Western visitors, was unable to believe that the Khmers could have built the temple, and mistakenly dated it to around the same era as Rome. The true history of Angkor Wat was pieced together only from stylistic and epigraphic evidence accumulated during the subsequent clearing and restoration work carried out across the whole Angkor site.
There were no ordinary dwellings or houses or other signs of settlement including cooking utensils weapons or items of clothing usually found at ancient sites. Instead there is the evidence of the monuments themselves. 
Angkor Wat required considerable restoration in the 20th century, mainly the removal of accumulated earth and vegetation. Work was interrupted by the civil war and Khmer Rouge control of the country during the 1970s and 1980s, but relatively little damage was done during this period other than the theft and destruction of mostly post-Angkorian statues.
The temple has become a symbol of Cambodia, and is a source of great national pride. A depiction of Angkor Wat has been a part of Cambodian national flags since the introduction of the first version circa 1863. In January 2003 riots erupted in Phnom Penh when a false rumour circulated that a Thai soap opera actress had claimed that Angkor Wat belonged to Thailand.
 Architecture  Site and plan A plan of Angkor WatAngkor Wat, located at 13°24′45″N 103°52′0″E / 13.4125°N 103.866667°E / 13.4125; 103.866667Coordinates: 13°24′45″N 103°52′0″E / 13.4125°N 103.866667°E / 13.4125; 103.866667, is a unique combination of the temple mountain, the standard design for the empire's state temples, the later plan of concentric galleries, and influences from Orissa and the Chola of Tamil Nadu, India. The temple is a representation of Mount Meru, the home of the gods: the central quincunx of towers symbolises the five peaks of the mountain, and the walls and moat the surrounding mountain ranges and ocean. Access to the upper areas of the temple was progressively more exclusive, with the laity being admitted only to the lowest level.
Unlike most Khmer temples, Angkor Wat is oriented to the west rather than the east. This has led many (including Glaize and George Coedès) to conclude that Suryavarman intended it to serve as his funerary temple. Further evidence for this view is provided by the bas-reliefs, which proceed in a counter-clockwise direction—prasavya in Hindu terminology—as this is the reverse of the normal order. Rituals take place in reverse order during Brahminic funeral services. The archaeologist Charles Higham also describes a container which may have been a funerary jar which was recovered from the central tower. It has been nominated by some as the greatest expenditure of energy on the disposal of a corpse.  Freeman and Jacques, however, note that several other temples of Angkor depart from the typical eastern orientation, and suggest that Angkor Wat's alignment was due to its dedication to Vishnu, who was associated with the west.
A further interpretation of Angkor Wat has been proposed by Eleanor Mannikka. Drawing on the temple's alignment and dimensions, and on the content and arrangement of the bas-reliefs, she argues that these indicate a claimed new era of peace under king Suryavarman II: "as the measurements of solar and lunar time cycles were built into the sacred space of Angkor Wat, this divine mandate to rule was anchored to consecrated chambers and corridors meant to perpetuate the king's power and to honor and placate the deities manifest in the heavens above." Mannikka's suggestions have been received with a mixture of interest and scepticism in academic circles. She distances herself from the speculations of others, such as Graham Hancock, that Angkor Wat is part of a representation of the constellation Draco.
The north-west tower of the inner gallery at sunset Style Angkor Wat is the prime example of the classical style of Khmer architecture—the Angkor Wat style—to which it has given its name. By the 12th century Khmer architects had become skilled and confident in the use of sandstone (rather than brick or laterite) as the main building material. Most of the visible areas are of sandstone blocks, while laterite was used for the outer wall and for hidden structural parts. The binding agent used to join the blocks is yet to be identified, although natural resins or slaked lime have been suggested.
Angkor Wat has drawn praise above all for the harmony of its design, which has been compared to the architecture of ancient Greece or Rome. According to Maurice Glaize, a mid-20th-century conservator of Angkor, the temple "attains a classic perfection by the restrained monumentality of its finely balanced elements and the precise arrangement of its proportions. It is a work of power, unity and style."
Architecturally, the elements characteristic of the style include: the ogival, redented towers shaped like lotus buds; half-galleries to broaden passageways; axial galleries connecting enclosures; and the cruciform terraces which appear along the main axis of the temple. Typical decorative elements are devatas (or apsaras), bas-reliefs, and on pediments extensive garlands and narrative scenes. The statuary of Angkor Wat is considered conservative, being more static and less graceful than earlier work. Other elements of the design have been destroyed by looting and the passage of time, including gilded stucco on the towers, gilding on some figures on the bas-reliefs, and wooden ceiling panels and doors.
The Angkor Wat style was followed by that of the Bayon period, in which quality was often sacrificed to quantity. Other temples in the style are Banteay Samré, Thommanon, Chao Say Tevoda and the early temples of Preah Pithu at Angkor; outside Angkor, Beng Mealea and parts of Phanom Rung and Phimai.
 Features Aerial view of Angkor Wat Outer enclosure The outer wall, 1024 by 802 m and 4.5 m high, is surrounded by a 30 m apron of open ground and a moat 190 m wide. Access to the temple is by an earth bank to the east and a sandstone causeway to the west; the latter, the main entrance, is a later addition, possibly replacing a wooden bridge. There are gopuras at each of the cardinal points; the western is by far the largest and has three ruined towers. Glaize notes that this gopura both hides and echoes the form of the temple proper. Under the southern tower is a statue of Vishnu, known as Ta Reach, which may originally have occupied the temple's central shrine. Galleries run between the towers and as far as two further entrances on either side of the gopura often referred to as "elephant gates", as they are large enough to admit those animals. These galleries have square pillars on the outer (west) side and a closed wall on the inner (east) side. The ceiling between the pillars is decorated with lotus rosettes; the west face of the wall with dancing figures; and the east face of the wall with balustered windows, dancing male figures on prancing animals, and devatas, including (south of the entrance) the only one in the temple to be showing her teeth.
The Temple viewed from the northwestThe outer wall encloses a space of 820,000 square metres (203 acres), which besides the temple proper was originally occupied by the city and, to the north of the temple, the royal palace. Like all secular buildings of Angkor, these were built of perishable materials rather than of stone, so nothing remains of them except the outlines of some of the streets. Most of the area is now covered by forest. A 350 m causeway connects the western gopura to the temple proper, with naga balustrades and six sets of steps leading down to the city on either side. Each side also features a library with entrances at each cardinal point, in front of the third set of stairs from the entrance, and a pond between the library and the temple itself. The ponds are later additions to the design, as is the cruciform terrace guarded by lions connecting the causeway to the central structure.
 Central structure This model of Angkor Wat shows intact the half-galleries of the lower level and towers at the corners of the second-level galleries.The temple stands on a terrace raised higher than the city. It is made of three rectangular galleries rising to a central tower, each level higher than the last. Mannikka interprets these galleries as being dedicated to the king, Brahma, the moon, and Vishnu. Each gallery has a gopura at each of the points, and the two inner galleries each have towers at their corners, forming a quincunx with the central tower. Because the temple faces west, the features are all set back towards the east, leaving more space to be filled in each enclosure and gallery on the west side; for the same reason the west-facing steps are shallower than those on the other sides.
The outer gallery measures 187 by 215 m, with pavilions rather than towers at the corners. The gallery is open to the outside of the temple, with columned half-galleries extending and buttressing the structure. Connecting the outer gallery to the second enclosure on the west side is a cruciform cloister called Preah Poan (the "Hall of a Thousand Buddhas"). Buddha images were left in the cloister by pilgrims over the centuries, although most have now been removed. This area has many inscriptions relating the good deeds of pilgrims, most written in Khmer but others in Burmese and Japanese. The four small courtyards marked out by the cloister may originally have been filled with water. North and south of the cloister are libraries.
Detailed plan.Beyond, the second and inner galleries are connected to each other and to two flanking libraries by another cruciform terrace, again a later addition. From the second level upwards, devatas abound on the walls, singly or in groups of up to four. The second-level enclosure is 100 by 115 m, and may originally have been flooded to represent the ocean around Mount Meru. Three sets of steps on each side lead up to the corner towers and gopuras of the inner gallery. The very steep stairways represent the difficulty of ascending to the kingdom of the gods. This inner gallery, called the Bakan, is a 60 m square with axial galleries connecting each gopura with the central shrine, and subsidiary shrines located below the corner towers. The roofings of the galleries are decorated with the motif of the body of a snake ending in the heads of lions or garudas. Carved lintels and pediments decorate the entrances to the galleries and to the shrines. The tower above the central shrine rises 43 m to a height of 65 m above the ground; unlike those of previous temple mountains, the central tower is raised above the surrounding four. The shrine itself, originally occupied by a statue of Vishnu and open on each side, was walled in when the temple was converted to Theravada Buddhism, the new walls featuring standing Buddhas. In 1934, the conservator George Trouvé excavated the pit beneath the central shrine: filled with sand and water it had already been robbed of its treasure, but he did find a sacred foundation deposit of gold leaf two metres above ground level.
 Decoration The bas-relief of the Churning of the Sea of Milk shows Vishnu in the centre, his turtle avatar Kurma below, asuras and devas to left and right, and apsaras and Indra above.Integrated with the architecture of the building, and one of the causes for its fame is Angkor Wat's extensive decoration, which predominantly takes the form of bas-relief friezes. The inner walls of the outer gallery bear a series of large-scale scenes mainly depicting episodes from the Hindu epics the Ramayana and the Mahabharata. Higham has called these, "the greatest known linear arrangement of stone carving". From the north-west corner anti-clockwise, the western gallery shows the Battle of Lanka (from the Ramayana, in which Rama defeats Ravana) and the Battle of Kurukshetra (from the Mahabharata, showing the mutual annihilation of the Kaurava and Pandava clans). On the southern gallery follow the only historical scene, a procession of Suryavarman II, then the 32 hells and 37 heavens of Hindu mythology.
Devatas are characteristic of the Angkor Wat style.Glaize writes of;
"... those unfortunate souls who are to be thrown down to hell to suffer a refined cruelty which, at times, seems to be a little disproportionate to the severity of the crimes committed. So it is that people who have damaged others' property have their bones broken, that the glutton is cleaved in two, that rice thieves are afflicted with enormous bellies of hot iron, that those who picked the flowers in the garden of Shiva have their heads pierced with nails, and thieves are exposed to cold discomfort."
On the eastern gallery is one of the most celebrated scenes, the Churning of the Sea of Milk, showing 92 asuras and 88 devas using the serpent Vasuki to churn the sea under Vishnu's direction (Mannikka counts only 91 asuras, and explains the asymmetrical numbers as representing the number of days from the winter solstice to the spring equinox, and from the equinox to the summer solstice). It is followed by Vishnu defeating asuras (a 16th-century addition). The northern gallery shows Krishna's victory over Bana (where according to Glaize, "The workmanship is at its worst") and a battle between the Hindu gods and asuras. The north-west and south-west corner pavilions both feature much smaller-scale scenes, some unidentified but most from the Ramayana or the life of Krishna.
 Construction techniques The stones, as smooth as polished marble, were laid without mortar with very tight joints that were sometimes hard to find. The blocks were held together by mortise and tenon joints in some cases, while in others they used dovetails and gravity. The blocks were presumably put in place by a combination of elephants, coir ropes, pulleys and bamboo scaffolding. Henri Mouhot noted that most of the blocks had holes 2.5 cm in diameter and 3 cm deep, with more holes on the larger blocks. Some scholars have suggested that these were used to join them together with iron rods, but others claim they were used to hold temporary pegs to help manoeuver them into place. The Khmer architects never made the curved arches used by the Romans. They did create a corbelled arch, but this often proved unstable and collapsed.
The monument was made out of enormous amounts of sandstone, as much as Khafre's pyramid in Egypt (over 5 million tons). This sandstone had to be transported from Mount Kulen, a quarry approximately 25 miles (40 km) to the northeast. The stone was presumably transported by raft along the Siem Reap river. This would have to have been done with care to avoid overturning the rafts with such a large amount of weight. One modern engineer estimated it would take 300 years to complete Angkor Wat today. Yet the monument was begun soon after Suryavarman came to the throne and was finished shortly after his death, no more than 40 years.
Virtually all of its surfaces, columns, lintels even roofs are carved. There are miles of reliefs illustrating scenes from Indian literature including unicorns, griffins, winged dragons pulling chariots as well as warriors following an elephant mounted leader and celestial dancing girls with elaborate hair styles. The gallery wall alone is decorated with almost 1,000 square meters of bas reliefs. Holes on some of the Angkor walls indicate that they may have been decorated with bronze sheets. These were highly prized in ancient times and were a prime target for robbers. While excavating Khajuraho, Alex Evans, a stone mason and sculptor, recreated a stone sculpture under 4 feet (1.2 m), this took about 60 days to carve.  Roger Hopkins and Mark Lehner also conducted experiments to quarry limestone which took 12 quarrymen 22 days to quarry about 400 tons of stone.  The labour force to quarry, transport, carve and install this much sandstone must have run into the thousands including many highly skilled artisans. The skill required to carve these sculptures was developed hundreds of years earlier, as demonstrated by some artifacts found that were dated to the seventh century before the Khmer came into power.  ...
 Angkor Wat today This model of Angkor Wat is designed to give tourists an overview of the site. In the foreground is depicted the cruciform terrace which lies in front of the central structure.The Archaeological Survey of India carried out restoration work on the temple between 1986 and 1992.  Since the 1990s, Angkor Wat has seen continued conservation efforts and a massive increase in tourism. The temple is part of the Angkor World Heritage Site, established in 1992, which has provided some funding and has encouraged the Cambodian government to protect the site. The German Apsara Conservation Project (GACP) is working to protect the devatas and other bas-reliefs which decorate the temple from damage. The organisation's survey found that around 20% of the devatas were in very poor condition, mainly because of natural erosion and deterioration of the stone but in part also due to earlier restoration efforts. Other work involves the repair of collapsed sections of the structure, and prevention of further collapse: the west facade of the upper level, for example, has been buttressed by scaffolding since 2002, while a Japanese team completed restoration of the north library of the outer enclosure in 2005. World Monuments Fund began work on the Churning of the Sea of Milk Gallery in 2008.
Angkor Wat has become a major tourist destination. In 2004 and 2005, government figures suggest that, respectively, 561,000 and 677,000 foreign visitors arrived in Siem Reap province, approximately 50% of all foreign tourists in Cambodia for both years. The influx of tourists has so far caused relatively little damage, other than some graffiti; ropes and wooden steps have been introduced to protect the bas-reliefs and floors, respectively. Tourism has also provided some additional funds for maintenance—as of 2000 approximately 28% of ticket revenues across the whole Angkor site was spent on the temples—although most work is carried out by foreign government-sponsored teams rather than by the Cambodian authorities.
