Angkor Thom , located in present day Cambodia, was the last and most enduring capital city of the Khmer empire. It was established in the late twelfth century by king Jayavarman VII. It covers an area of 9 km², within which are located several monuments from earlier eras as well as those established by Jayavarman and his successors. At the centre of the city is Jayavarman's state temple, the Bayon, with the other major sites clustered around the Victory Square immediately to the north.
Angkor Thom was established as the capital of Jayavarman VII's empire, and was the centre of his massive building programme. One inscription found in the city refers to Jayavarman as the groom and the city as his bride.
Angkor Thom seems not to be the first Khmer capital on the site, however. Yasodharapura, dating from three centuries earlier, was centred slightly further northwest, and Angkor Thom overlapped parts of it. The most notable earlier temples within the city are the former state temple of Baphuon, and Phimeanakas, which was incorporated into the Royal Palace. The Khmers did not draw any clear distinctions between Angkor Thom and Yashodharapura: even in the fourteenth century an inscription used the earlier name. (Higham 138) The name of Angkor Thom — great city — was in use from the 16th century. Ta Prohm Tempel in Cambodia
Ta Prohm is the modern name of a 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 has been left 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. The conservation and restoration of Ta Prohm is a partnership project of the Archaeological Survey of India and the APSARA (Authority for the Protection and Management of Angkor and the Region of Siem Reap).
