The Great Banyan is a banyan tree (Ficus benghalensis) located in Acharya Jagadish Chandra Bose Indian Botanic Garden, Howrah, near Kolkata, India. It was the widest tree in the world in terms of the area of the canopy and is estimated to be about 1200 to 1250 years old. It became diseased after it was struck by lightning, so in 1925 the middle of the tree was excised to keep the remainder healthy; this has left it as a clonal colony, rather than a single tree. A 330 metre long road was built around its circumference, but the tree continues to spread beyond it.
