Chennai is the headquarters for the 'theosophical society'. It is located along the river Adyar. In 1882 Blavatsky and col. Oleott formed a society with an aim to comparatively study religion, philosophy and science.

The society was initially located in the U.S.A but later it was shifted to Adyar. The huge Banyan tree with a span of 40,000 sq. ft serves as the place where the discourses are given. This place has got shrines of almost all faiths and a 95 years old library with a rare collection of books and manuscripts many of which are written on palm leaves and parchments.
