Angkor Wat (or Angkor Vat), a World Heritage Site,
is a temple at Angkor, Cambodia, built for King Suryavarman II in the
early 12th century as his state temple and capital city. As the
best-preserved temple at the site, it is the only one to have remained a
significant religious centre since its foundation—first Hindu,
dedicated to Vishnu, then Buddhist.

The
temple is the epitome of the high classical style of Khmer
architecture. It has become a symbol of Cambodia, appearing on its
national flag, and it is the country's prime attraction for visitors.
Angkor Wat combines two basic plans of Khmer temple
architecture: the temple mountain and the later galleried temple. It is
designed to represent Mount Meru, home of the gods in Hindu mythology:
within a moat and an outer wall 3.6 km (2.2 miles) 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.
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 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.
