Cambodia Ta Prohm

Ta Prohm is the modern name of the temple at Angkor, Siem Reap Province, Cambodia, built in the Bayon style largely in the late 12th and early 13th centuries and originally called Rajavihara. Located approximately one kilometre east of Angkor Thom and on the southern edge of the East Baray, it was founded by the Khmer King Jayavarman VII as a Mahayana Buddhist monastery and university. Unlike most Angkorian temples, Ta Prohm is in much the same condition in which it was found: the photogenic and atmospheric combination of trees growing out of the ruins and the jungle surroundings have made it one of Angkor's most popular temples with visitors. UNESCO inscribed Ta Prohm on the World Heritage List in 1992. Today, it is one of the most visited complexes in Cambodia’s Angkor region.
