History and description

The Great Banyan tree is over 250 years old and in spread it is the largest known in India, perhaps in Asia. There is no clear history of the tree, but it is mentioned in some travel books of the nineteenth century. It was damaged by two great cyclones in 1884 and 1886, when some of its main branches were broken and exposed to the attack of a hard fungus. With its large number of aerial roots, The Great Banyan looks more like a forest than an individual tree. The tree now lives without its main trunk, which decayed and was removed in 1925. The circumference of the original trunk was 1.7 m and from the ground was 15.7 m. The area occupied by the tree is about 14500 square metres (about 1.5 hectare
