Kasi Viswanathar Paramathivelur is an east-facing temple with a 3 tiered Rajagopuram on the east side and surrounded by a high compound wall. A single Prakaram houses the shrines and sanctum sanctorum. There are cloistered mandapams on the south side of the Prakaram. The pillars in the Mandapams have some nice carvings and there are a lot of Fish symbols on the mandapam and compound walls. There is a small gate and gopuram on the south side facing the Cauvery River that flows just beyond the walls of the temple. There is a crematorium next to the Kasi Viswanathar Paramathivelur temple. Kasi Viswanathar Paramathivelur is presently undergoing major renovation work and the shrines and sanctum niches are awaiting completion and installation of deities.
