The Great Banyan Tree located in Acharya Jagadish Chandra Bose Indian Botanic Garden, Howrah, near Kolkata, India, is the widest tree in the world in terms of the area of the canopy it covers. It is estimated to be about 200 to 250 years old and occupies an area of about 14,500 square meters (1.5 hectares).
With its large number of aerial roots, the Great Banyan Tree 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 present crown of the tree has a circumference of about 1 kilometre and the highest branch rises to about 25 m; it has at present 2880 aerial roots reaching down to the ground.
