Ta Prohm is the modern name of what was originally called Rajavihar. Built in the Bayon style in the late 12th century Ta Prohm was founded as a Buddhist monastery and university. Unlike most renovated Angkor temples, Ta Prohm has been left in pretty much the same condition in which it was found - the roots and trees have become so much a part of the structures that if removed the structures would lose their integrity. The atmospheric combination of trees growing out of the ruins and the natural surroundings have made the temple one of Angkor's most popular with visitors. The trees growing out of the ruins are of two species: the silk cotton tree ceiba pentandra or Tetrameles nudiflora and the strangler fig or Ficus gibbosa.
