The Brihadeeswarar Temple was built to grace the throne of the Chola empire by the Tamil emperor Arulmozhivarman, popularly called Rajaraja Chola I, in compliance to a command given to him in a dream. One of the first great Tamil Chola building projects, the temple's foundations were laid out in 1002 CE. An axial and symmetrical geometry rules the temple layout. Temples from this period and the following two centuries are an expression of the Tamilars (Chola) wealth, power and artistic expertise.
