The temple was erected during the Parantaka I reign 907-955 A.D.  The sanctum is akin to Vaprabandha type with Arthapadma, a feature not mentioned in Vastu Shastra texts.  The beautiful large vyalas in the prathimukha are among the most powerfully conceived of their kind.  It is of modest proportions and consists of the sanctuary and its attached mandapam(hall).  The two cover a total length of 15.3m, with its vimana measuring about 15.3m.  The mandapam is a hall of 4 central pillars, and a vestibule provided at its back, leading to the sanctum, which is a square chamber of 3.7m.  The lion motif is absent in the pillars though it reappeared in friezes where ever suited.  The pillars in the interior are typical of Chola art.  The usual deities are enshrined in the central niches outside the wall of the sanctum.  The toranas over the south and west niches are of good workmanship, especially that on the west, which is perhaps the finest in South India
