There are a number of festivals celebrated almost every month at the Pataladri Narasimhasvami temple of Singaperumalkoil. Singaperumalkoil is a census town located in Chennai metropolitan city in the Tamil Nadu state of India. It is acknowledged by the name of Pataladri Temple, because here Lord Narasimha is in his Ugra Roopa. Narasimha is one of the incarnations of Lord Vishnu, who is half-man and half-lion. As per the mythological story, it is believed that at the request of Sage Jabali, Narasimha, Singaperumal or the Lion God, manifested himself immediately after he packed off Hiranyakashyapu to the nether world. The festivals of Pataladri Narasimhasvami temple reveal its cultural significance. The festivals are organized with immense pomp and grandeur during which a number of devotees gather in the temple complex to offer their worship to the lord.
