Perumukkal is a small village in the Tindivanam municipality of the Villuppuram district in the Indian state of Tamil Nadu.

Local people believe Sita, the central female character in the Hindu epic Ramayana, lived in this cave.

In 1761[citation needed] it was captured by Sir Eyre Coote of the British East India Company.

The deity of the temple is known as Tiruvanmikai Eswaramudayar, as well as Perumukkal Udayar in Tamil (பெருமுக்கல் உடையார்) and Mukthiyaleeswarar in Sanskrit.

The donations made by the Chola, Pandya, Sambuvaraya, Vijayanagara rulers have been recorded in more than 60 Vatteluthu inscriptions found on the temple walls dating back to the 7th century C.E.
