Thirumanimadam or Narayanan Perumal Temple is dedicated to Hindu god Vishnu located in Thirunangur, a village in the outskirts of Sirkazhi in the South Indian state of Tamil Nadu. Constructed in the Dravidian style of architecture, the temple is glorified in the Divya Prabandha, the early medieval Tamil canon of the Azhwar saints from the 6th–9th centuries AD. It is one of the 108 Divyadesam dedicated to Vishnu, who is worshipped as Narayanan and his consort Lakshmi as Pundarikavalli.
It is one among the eleven divyadesams of Thirunangur Tirupathis and is closely associated with Thirumangai Alvar. The temple is open from 8 a.m. to 10 a.m. and 5 p.m. to 7 p.m and has four daily rituals at various times of the day. The Thirumangai Azhwar Mangalasasana Utsavam celebrated annually during the Tamil month of Thai is the major festival of the temple during which the festival images of the eleven Thirunangur Tirupathis are brought on mount designed like Garuda, called Garuda Vahana, to Thirunangur.
The legend of all the eleven temples of Thirunangur are closely associated with each other. As per legend, the Hindu god Shiva started dancing in fury at this place after the death of his consort Uma due to the yagna (sacrifice) of Daksha. Each time his lock of hair touched the ground, there were eleven other forms of Shiva who appeared. The celestial deities were worried that if the dance continues, it would result in decimation of entire creations. They prayed to Vishnu for help, who appeared at this place. On seeing Vishnu, Shiva's anger was reduced and he requested Vishnu to appear in eleven forms like he did. On his request, Vishnu appeared in eleven different forms at Tirunangur. The eleven places where Vishnu appeared are believed to be where the eleven temples in Tirunangur are located. The eleven Rudras, called Ekadas Rudras and king of devas, Indra, are believed to have worshiped Vishnu at this temple. The presiding deity of Badrinath Temple, Badrinath, is believed to have visited the place on the request of Shiva. Ramanuja is believed to have learnt Tirumandiram from Thirukoshtiyur Nambi at this place.
It is located in Thirunangur, a small village, 10 km away from Sirkali en route to Thiruvenkadu. The temple tank is located right across the temple. Inscriptions from 10th-century Chola and Nayakkar periods are seen in the temple.
