Description: This Dhivya Desam is located in the village of Thalaichchangaadu, near Aakkur, near Sirkazhi. Sirkazhi is located on the route between Chidambaram and Mayiladuturai. The Thirutthalaichankaadu Shivasthalam glorified by the Thevaram hymns is also located here.
Deities: The Moolavar is Naanmadiyapperumaal (Venchudarpperumaal) in a standing posture facing east; Taayaar here is Thalaichchanga Naachiyaar. The Utsavars are Vyomajyotipiraan and Senkamalavalli. A priceless conch adorns the image of Naanmadiyapperumal; the image of Andal here is of great beauty.
Legend in the Shivasthalam enshrining Shankharunaatheswarar in this village holds that Vishnu was blessed with a conch (the foremost of all conches - Thalai Changu) upon worshipping Shiva. Thirutthalaichankaadu is also known as Shankharanyam or Shankhuvanam.
