When you are visiting Anuradhapura, the most crowd would undoubtedly be found at Sri Maha Bodhiya. It is the sacred Bo Tree of the Buddhists, held in highest esteem by those of the faith. According to history, Sri Maha Bodhiya is an offshoot of the Bo Tree under which Lord Buddha attained enlightenment. Thus, it is a highly sacred place of worship among the Buddhists, who have special rituals that revolve around the tree. It is also one of the oldest trees in the world and has seen the passing of over 20 centuries. Male devotees are allowed to go to the "uda maluwa", the upper part of the structure, which is the closest a lay person is allowed to come to the tree.
