Ranganathan Swamy temple is located at Karamadai, Coimbatore on the Coimbatore-Mettupalayam highway about (23kms) and is about 2000 years old temple.
Also known as Aranganathar Swamy, the main deity here is Lord Vishnu in the name of Ranganathar and Goddess Lakshmi is in name of Ranganayaki.
It is believed that decades back, a man from the thottiyyar’s tribe followed a cow to the woods that refused to give milk for a few days.
The cow was seen shedding its milk on a stone. In a fit of rage, the man struck the stone with a cane and blood started oozing out. Then, as per the Asariri (Godly Voice), a temple was erected there.
