Preah Khan Kompong Svay

The archeological complex of Preah Khan (of) Kampong Svay (Khmer: ព្រះខ័ននៅកំពង់ស្វាយ) or Prasat Bakan (according to local pronunciation) or Bakan Svay Rolay is located 100 km east of Angkor, in Preah Vihear province, Cambodia. It stands as the largest single religious complex ever built during Angkorian Era, as its exterior enclosure is about 5 km square, even if the isolated location makes it one of less visited Angkorian sites.
