Behind the back of the Thirumayam fort (detailed blog) entrance, you will find Sathyamurthi Perumal Temple [ஸ்ரீ சத்யமூர்த்திப் பெருமாள் திருக்கோயில், திருமயம்]. It is one of the 108 Divyadesam dedicated to Vishnu, who is worshipped as Sathyamurthi Perumal and his consort Lakshmi as Ujeevana Thayar. The temple is glorified in the Divya Prabandha by Azhwar saints from the 6th–9th centuries AD. The temple has the largest idol of Lord Vishnu in his reclining pose (சயனத்திருக்கோலம்) carved inside a natural cave.
After Thirumayam our next stop was Kanadukathan (கானாடுகாத்தான்) to see the Chettinad palaces there.
