The Pralayakalesvara temple at Pennakadam is wholly apsidal - one of the few kinds in the Chola country. Another example of an apsidal temple is the main temple at Muyarchchinadesvarar; a large number of apsidal temples are however found in Tondai-nadu. This is a small-medium, single storeyed (alpavimana), east facing temple. An interesting feature of this temple is that the gable is profusely covered with modern stuccowork. Reference: S.R.
