Azhagaputhur Guru Navasakthi Temple

A UNESCO World Heritage Site (Great Living Chola Temples group) built by Raja Raja Chola II in the 12th century CE. Lord Airavateswara (Shiva worshipped by Airavata, Indra's white elephant) is enshrined here. The temple's 'chariot steps' carved to look like a stone chariot and the extraordinary sculptures of Yama, the god of death, are extraordinary.

The Rahu (ascending lunar node) Navagraha temple near Kumbakonam, where the presiding deity is Naganatha Swamy (Shiva). Uniquely, Rahu is said to turn white during his worship here — an observed natural phenomenon. The main lingam glows with a mysterious blue light on Rahu worship days. One of the most powerful Navagraha temples.

The principal Shiva temple of Kumbakonam and one of the most important in Tamil Nadu. Lord Kumbeswarar (Shiva who formed the universe from a 'kumba'/pot of nectar) is worshipped here. During the rare Mahamaham festival (once in 12 years), lakhs bathe in the sacred Mahamaham tank adjacent to the temple — the largest religious gathering in Tamil Nadu.

The fourth Arupadaiveedu, where Murugan taught the Pranava Mantra (Om) to his own father Shiva. The deity here is Swaminatha — Murugan as the teacher of his parent. Located near Kumbakonam, easily combined with the Navagraha temple circuit.
