Located in the Indian Botanical Gardens, Howrah, over the River Hooghly from Kolkata, the Great Banyan was the widest tree in the world, in terms of the area of the canopy. It is estimated as about 200 to 250 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 330m road was built around its circumference, but the tree continues to spread beyond it.
