Bodhigara, the Bodhi tree building
Near the Viharn Geng and Viharn Phra Sasada is a building known as Bodhigara, a structure to protect a Bodhi tree. The original tree which is believed to be an offspring of the tree under which the Buddha reached enlightenment some 2,500 years ago was planted by King Mongkut. Since this tree has not survived, King Bhumibol planted another tree, which is also an offspring of the Bodhi tree in India.
