The Bodhi Tree, also known as Bo (from the Sinhalese Bo), was a large and very old Sacred Fig tree (Ficus religiosa) located in Bodh Gaya (about km ( mi) from Patna in the Indian state of Bihar), under which Siddhartha Gautama, the spiritual teacher and founder of Buddhism later known as Gautama Buddha, is said to have achieved enlightenment, or Bodhi. In religious iconography, the Bodhi tree is recognizable by its heart-shaped leaves, which are usually prominently displayed.
