Anuradhapura (ənōˈrädəpōˈrə) [key] or Anarajapura ənäˈräjə–, city (1995 est. pop. 40,000), N central Sri Lanka, on the Aruvi River. Rice plantations and vegetable gardens surround the city, which is famous chiefly for its vast Buddhist ruins and as a pilgrimage center. Founded in 437 B.C., it was the capital of a Sinhalese kingdom and a Buddhist center until the 8th cent. A.D., when, after a Tamil invasion, it was abandoned in favor of Pollonarrua. Ruins include several colossal stupas (some larger than the pyramids of Egypt), a temple hewn from rock, and the Brazen Palace (so called from its metal roof). A sacred bo tree at Anuradhapura was grown from a slip of the tree at Bodh Gaya, India, under which Buddha reputedly attained enlightenment. The Archaeological Survey of Sri Lanka has its headquarters in the city.
