Singaperumal Kovil is a legendary place and is known by the name of the deity. The name of the deity is derived from the Sanskrit name Pataladri as this hillock (adri) into which the cave-temple has been carved is reddish (patala) in appearance. Although the principal deity here is now known as Pataladri Narasimhasvami and this place is called Singaperumal Kovil, the ancient inscriptions found in this shrine reveal that this deity was known by various other names in the distant past. The names with which the deity was known in the ancient times are Azhvar Narasinga Vinnagar Deva and Narasinga Vinnagar Azhvar. This sacred place where the temple is erected was originally known as Chengunram (red hillock) and was part of the territorial sub-division called Chengunra Nadu situated in the region of Kalattur-kottam. Pataladri is thus the Sanskrit variant of Chengunram, the ancient Tamil name for this sanctified spot.
