Beng Mealea or Bung Mealea (Khmer: ប្រាសាទបឹងមាលា, its name means "lotus pond"[1]) is a temple in the Angkor Wat style located 40 km east of the main group of temples at Angkor, Cambodia, on the ancient royal highway to Preah Khan Kompong Svay.
galleries around a central sanctuary, collapsed at present. The enclosures are tied with "cruciform cloisters", like Angkor Wat. Structures known as libraries lie to the right and left of the avenue that leads in from the east. There is extensive carving of scenes from Hindu mythology, including the Churning of the Sea of Milk and Vishnu being borne by the bird god Garuda. Causeways have long balustrades formed by bodies of the seven-headed Naga serpent.
It was built mostly of sandstone: Beng Mealea is only 7 km far from the angkorian sandstone quarries of Phnom Kulen, as the crow flies. Presumably sandstone blocks used for Angkor were transported along artificial water canals and passed from here.[1] Despite of lack of information, the quality of architecture and decorations has drawn the attention of French scholars just from its discovery.
