Cambodia March 24, 2014: Angkor Wat was first a Hindu, then subsequently a Buddhist, temple complex in Cambodia and the largest religious monument in the world. The temple was built by the Khmer King Suryavarman II in the early 12th century in Yasodharapura, the capital of the Khmer Empire, as his state temple and eventual mausoleum. Breaking from the Shaivism tradition of previous kings, Angkor Wat was instead dedicated to Vishnu. As the best-preserved temple at the site, it is the only one to have remained a significant religious center since its foundation. The temple is at the top 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, based on earlyDravidian 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 adorning its walls.

The modern name, Angkor Wat, means "Temple City" or "City of Temples" in Khmer; Angkor, meaning "city" or "capital city", is a vernacular form of the word nokor (នគរ), which comes from the Sanskrit word nagara (नगर). Wat is the Khmer word for "temple grounds", derived from the Pali word "vatta" (वत्त). Prior to this time the temple was known as Preah Pisnulok (Vara Vishnuloka in Sanskrit), after the posthumous title of its founder.

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 and 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.
