This Sthalam is situated in Tamil Nadu, Chengulpet District. We can reach the temple by travelling around 4 Kms from Pallavaram Railway Station, which is about 7 Kms from Chennai.
In this Sthalam, the Perumal is found is various positions as Nindraan, Irunthaan, Kidanthaan and Nadanthaan Thirukkolam.
It is said that once Thirumangai Alwar came here to get the Dharshan of the Perumal. At that time, the mountain was fully surrounded by water and he waited for six months to worship the Perumal. After all the water drained, he went up the mountain and worshipped the Perumal. The place where Thirumangai Alwar stayed is called as "Thiru Mangai Alwarpuram".
There are two temples, one on the top of a hill and one on the base of the hill. The Thiruneermalai Perumal Temple on the top of the hill is dedicated to Sri Vishnu as Ranganatha Perumal. The temple at the foot of the hill is dedicated to Sri Vishnu as Neervanan Perumal.
