मल्लपुरम्

The moolavar is Stalasayana perumal in a reclining posture and the Thayar Nilamangai Thayar. The Theertham is Pundarika puskharini and the Vimanam Gaganakriti Vimanam.

According to the sthala purana Pundareeka Maharshi desirous of worshipping Lord Vishnu with lotus flowers, proceeded eastward and was trying to drain the waters of the ocean to make his way. The Lord came in the guise of an old man and asked for some food. The Maharishi went to fetch him some food, and when he returned he found Lord Vishnu adorning Himslef with the flowers and giving darsan as Ananthasayanam. Hence this place gained the name Sthalasayanam.

Maasi Makham festival is an important event.
