The Airavatesvara temple at Darasuram (Tamil Nadu) has highly ornate execution. The temple consists of a sanctum without a circumambulatory path and halls or mandapas. The Airavatesvara temple, in the inscriptions known as Rajarajesvara temple, was built by Rajaraja II, of Kulottunga’s line, who ruled from 1146 to 1172 CE. The front mandapa known in the inscriptions as Rajagambhiran tirumandapam is unique as it is conceived as a chariot with wheels. This temple is reminiscent of the Melakkadambur temple built by Kulottunga I (1111 CE) and anticipates the giant wheel Konark temple at Orissa (1235-53 CE).
It is one of the greatest monuments and the last Chola enterprise of this scale. The temple faces the east. There is an open court, a double-storeyed cloister with just a single entrance in the east. There was an outer enclosure but it has totally vanished. There is a Nandimandapa, and a Balipitha or platform for offerings. The main temple consists of a vimana, ardhamandapa, a transept, a closed large hall or mahamandapa and a mukhamandapa. Wheels of stone at regular intervals are suggestive of the divine chariot of Shiva.
The pillars of this mandapa are highly ornate. The elevation of all the units is elegant with sculptures dominating the architecture. A number of sculptures from this temple are the masterpieces of Chola art. The labelled miniature friezes extolling the events that happened to the sixty-three (63) Tamil saints - Nayanamars are noteworthy and reflect the deep roots of Saivism in this region. The Airavatesvara temple complex itself has been entirely built at the same time with no later additional structures and remains in its original form.
The Daivanayaki Amman shrine, built a little later, also stands in its original form within its own enclosure. The construction of a separate temple for Devi indicates the emergence of the Amman shrine as an essential component of the South Indian temple complex. The shrine is interesting from architectural, sculptural and cultic points of view. The temple shares with Airavatesvara the blend of Saiva and Sakta doctrines that were in vogue during these times.
