Angkor Wat is a large Hindu/Buddhist temple complex located in Siem Reap, Cambodia that was constructed in the early 12th century AD. It is the largest religious monument in the world, covering an area larger than Paris. The architecture is representative of the classical Khmer style, using sandstone blocks for the visible areas and laterite for the outer wall. It combines elements of the temple mountain and galleried temple designs, intended to represent the Hindu Mount Meru, and is surrounded by a moat and outer wall.
