The Great Living Chola Temples were built by kings of the Chola Empire, which stretched over all of south India and the neighbouring islands. The site includes three great 11th- and 12th-century Temples: the Brihadisvara Temple at Thanjavur, the Brihadisvara Temple at Gangaikondacholisvaram and the Airavatesvara Temple at Darasuram. The Temple of Gangaikondacholisvaram, built by Rajendra I, was completed in 1035. Its 53-m vimana (sanctum tower) has recessed corners and a graceful upward curving movement, contrasting with the straight and severe tower at Thanjavur. The Airavatesvara temple complex, built by Rajaraja II, at Darasuram features a 24-m vimana and a stone image of Shiva. The temples testify to the brilliant achievements of the Chola in architecture, sculpture, painting and bronze casting.
