Tirucadavoor: 18 kms. from Mayuram. There is an ancient Shiva temple at this place which is associated with the life of Markandeya. The Lord is known as Amrithachaleshwarar and the goddess is called Abhirami Amman. A special feature of this temple is in the Shanku Mantapam (hall of conches) where several huge conches are filled with water and later used for Abhishekam of the deity. There are two sacred ponds in the enclosure called Markandeya Tirtha and Amrith Tirtha.
