History of the Temple
This temple is around 1500 years old and was built in the Chola period. “Killi” is the surname of Chola kings and there are historical references to kings from the Chola period like King Nedungkilli and King Killivalavan. It is possible that this place’s name “Kiliyanur” might have been derived from its connection to the Chola dynasty.
As per the stone inscriptions in the temple, it can be deduced that this temple was first built using bricks and later reconstructed using granite during King Paranthaka Chola-I’s period.
Legend
It is said that the lingam (Moolavar) was installed and worshiped by Sage Agasthiyar, so the lord is named Sri Agastheeswarar.
It is also said that Nandi Devar (the bull which serves as the mount of Lord Shiva), who is in front of Goddess Akilandeswari is performing poojas and worshiping her on Maha Shivratri days. Some inscriptions about this are also available in this temple.
