The Great Living Chola Temples are temples built during the Chola rule in the south of India. These temples are the Brihadisvara Temple at Thanjavur, the Temple of Gangaikondacholisvaram and the Airavatesvara Temple at Darasuram. The Brihadisvara Temple was declared by UNESCO as a World Heritage Site in 1987; the Temple of Gangaikondacholisvaram and the Airavatesvara Temple at Darasuram were added as extensions to the site in 2004. The site is now known as the "Great Living Chola Temples".
