This is actually siddhi vinayakar temple which is located in morrison street near cement road in Alandur, Chennai. On entering the temple we felt that it is indeed a samadhi we felt exactly the same experience as one would enter a samadhi temple. Such an immense depth and stillness!!!
In fact the name of the temple is siddhi vinayakar temple. Later our Guruji confirmed it and told that the name of the saint is theerthagireeswarar and He came from Rameswaram and attained samadhi here when He was 85 years old.
