Thirumalai Vaiyaavoor has a beautiful temple for Sri Prasanna Venkatesa Perumaal on a small hill, which is also called Thirumalai. Goddess here is Sri Alarmel Mangai Thaayaar.
Sri Rama after the battle with Raavana came here, bathed in Varaaha Theertham and worshipped the Lord, on His way back to Ayodhya.
Sri Ramanuja had worshipped the Lord here and named the place ‘Vaikundagiri’. He also had stayed in this place and meditated the Lord. Hence this place is also called as Ramanuja Yogagiri.
Tihs temple is 72 kms from Chennai and 18 kms from Chengalpattu. After crossing Chengalpattu, one can find Padaalam Cross Road (Koot Road) from where a road goes off GST Road on the right side. Drive this road for few kilometers you can find the darshan of the Temple with Gopuram from the distance.
