HistoryAngkor 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, 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
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.
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 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.
