All three temples, the Rajarajiswaram at Thanjavur, the Gangaikondacholiswaram at Gangaikondacholapuram and Airavatisvara at Darasuram, are all living temples located within the Kaveri Delta region, the heart of Chola Empire. The tradition of temple worship and rituals established and practiced over a thousand years ago, based on still older Agamic texts, continues daily, weekly and annually, as an inseparable part of life of the people.
