The Great Living Chola Temples, built by kings of the Chola Empire stretched over all of Tamil Nadu. This cultural heritage site includes three great temples of the 11th and 12th centuries namely, 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 metres (174 ft) 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 metres (79 ft) vimana and a stone image of Shiva. The temples testify to the brilliant achievements of the Chola in architecture, sculpture, painting and bronze casting. The site was inscribed under the UNESCO World Heritage List in 1987 as Cultural heritage under criteria (ii) and (iii).
