Brihadeshvara, also called Rajarajeshvara after its founder (Rajaraja I, 985 - 1012), was built from 1003 to 1010. It is the greatest of Chola temples, and was one of the largest structures in the world at the time. Its thirteen-storied tower (all temple towers in India have an odd number of stories) is about 66m (200ft) tall. The temple is dedicated to the worship of Shiva.
