Top tourist attraction of Anuradhapura, Sri Maha Bodhiya (Bodhi Tree) is a large and very old sacred Fig tree that is believed to be the oldest living tree in the world. Sanghamitta Theri brought the right branch of the Bodhi Tree (under which Buddha attained enlightenment in Bodh Gaya) to Anuradhapura in 245 BC. Bodhi tree was planted by Devānāmpiyatissa with assistance by the nobles of Kājaragāma, Candanagāma and Tivakka. Bodhi Tree of Anuradhapura is one of one of the most sacred relics in Sri Lanka that is frequented by Buddhist tourists from all over the world. The wall around the Bodhi Tree was built during the reign of King Kirthi Sri Rajasingha, to protect it from wild elephants.
