Brihadeeswarar Temple, Gangaikondacholapuram[edit]

Brihadisvara Temple at Gangaikonda Cholapuram is a Hindu temple dedicated to Shiva in Gangaikonda Cholapuram, Jayankondam, in the South Indian state of Tamil Nadu. Completed in 1035 AD by Rajendra Chola I as a part of his new capital, this Chola dynasty era temple is similar in design, and has a similar name, as the older 11th century, Brihadeeswarar Temple about 70 km (43 mi) to the southwest in Thanjavur. The Gangaikonda Cholapuram Temple is smaller yet more refined than the Thanjavur Temple. Both are among the largest Shiva temples in South India and examples of Dravidian style temples.
