Mostly built in typical Dravida style  architecture,  each one has immense historical value. Most of them are dedicated to various forms of Vishnu and in the case of Shiva temples  go by different names because Shiva has no avatar.

Brahmanda Purana, Naradiya Purana and Skanda Purana made a mention of this temple.  A group of  sages  wanted to know the sacred divinity of God Vishnu. Their visits to places like Thiruparkadal, Vaiunta did not get the needed results. Having searched so many places at last they located a place where sage Markandaya  and his daughter Bhudevi  were busy mediating on God Vishnu. They could see  Mahavishnu/ Empiron  in all his splendor  and dazzling beauty  with his his weapons Sudarshana (wheel), Panchajanya (conch) and Kaumodaki gracing his arms.

Legend Has it God Vishnu had his mount Garuda (Eagle vahana) bring the holy water (theertham) from  lake Vraja Theertha in  the neither world. It was secretly established by the sage. Upon seeing Garuda taking water from the lake, the sage was in rage and turned the water impure. Garuda  then  explained to him about his mission as ordered by God Vishnu.  As considerable time was lost  due to arguments between garuda and the learned sage, Vishnu asked  Adishesha to get pure water from the earth through a hole by whipping his tail.  The temple ''offerings'' or Prasadams are prepared using the water from the ancient well.
