Beng Mealea or Bung Mealea (Khmer: ប្រាសាទបឹងមាលា, its name means "lotus pond") 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.
It was built as a Hindu temple, but there are some carvings depicting buddhist motifs. Its primary material is sandstone and it is largely unrestored, with trees and thick brush thriving amidst its towers and courtyards and many of its stones lying in great heaps. For years it was difficult to reach, but a road recently built to the temple complex of Koh Ker passes Beng Mealea and more visitors are coming to the site, as it is 77 km from Siem Reap
The history of the temple is unknown and it can be dated only by its architectural style, identical to Angkor Wat, so scholars assumed it was built during the reign of king Suryavarman II in the early 12th century. Smaller in size than Angkor Wat, the king's main monument, Beng Mealea nonetheless ranks among the Khmer empire's larger temples: the gallery which forms the outer enclosure of the temple is 181 m by 152 m. It was the center of a town, surrounded by a moat 1025 m by 875 m large and 45 m wide.
Beng Mealea is oriented toward the east, but has entranceways from the other three cardinal directions. The basic layout is three enclosing 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.This site was added to the UNESCO World
Heritage Tentative List on September 1, 1992 in the Cultural category.
