Singaperumal cave temple is a located in Chennai metropolitan city Kancheepuram district in the Indian state of Tamil Nadu.
The village itself is named after the deity of this temple. The main deity here is Lord Narasimhar. The Lord Ugra Narasimha resides inside a cave in Yoga Posture. This is the posture in which the Lord gave Darshan to Jabali Rishi as per his wishes. This is a beautiful rock cut temple. The temple and even the deity are carved out of a small hillock. Here the Lord is known as Sri Paatalaadri Narasimhar. In Sanskrit Paatalaadri means a reddish hill. The original name of this place itself is Paatalaadripuram.
The main sanctum itself is a rock cut shrine on which the deity too is carved out of the hill itself. So, whoever wants to circumambulate around the temple has to actually go around the small hillock as Giri Pradhakshinam. Hence, Giri Pradhakshinam is very popular here.
