Namakkal Anjaneyar Temple

It is believed that when Lord Hanuman was having a bath in Kandaki River in Nepal, He stumbled across a stone which was in the shape of Lord Vishnu. When He was passing through the place,  He saw Goddess Lakshmi medicating here. Upon asking, She said She had come to the place for penance after Lord Narasimha kills Hiranyakashyap, the king who troubled his son Prahlada. Lord Hanuman wanted to have a bath, but couldn't go ahead as He was carrying the Salagrama (stone), which shouldn't be placed on the Earth. 

He asked the goddess to hold it until He returned. Goddess Lakshmi warns that if He doesn't return within the stipulated time, She will put it down  Upon returning, Hanuman finds that the stone was placed on the ground, and also, that it is now impossible to be moved. The stone grows into a mountain. It is here that Lord Narasimha Swamy appears before both of them and wishes to make the place His abode. 

Hence, today we see Hanuman is seen in a posture which indicates that He is paying his obeisance to Lord Narasimha Swamy, whose temple is located just 150 km away. There is also the hillock that is believed to have been brought by Lord Hanuman from Nepal. There is a Rock Fort or Namakkal fort located on the hillock.
