The long prakaram surrounds the great temple (500 feet/250 feet), and the walls surrounding the prakaram again go back to Raja Raja Cholan's period. The walls house long pillared corridors, which abound in murals, Shiva Lingams and Nandis. The Periya Nayaki temple within the temple is a later addition from the Pandya period, and so is the Subramanyar Temple sung later by the Saint poet Arunagirinathar.
Incidents from the lives of the Nayanmars, several of the 108 Bharata Natyam Dance postures, manifestations of Shiva (Aadalvallaan - Nataraja, Tripurantaka, Dakshinamurthi etc.) are depicted in sculptured panels or in exquisite Chola murals. Both the interior, and the exterior walls of the temple, are replete with images of the kind described above.
The sanctum, the ardhamandapam, the mukhamandapam and the Mahamandapam, although distinct, form a composite unit with an imposing appearance that awes visitors, forcing one to wonder how such timeless architectural feat was executed about a 1000 years ago. Entrances to the Mandapams and the towered entrances to the Prakarams are majestic. The grandeur of the architecture and the sculptural finesse speaks volumes of the skills of the Imperial Cholas.
Inscriptions refer to Shiva as Dakshina Meru Vitankar and Aadavallan. The Nandi, which dates back to the Nayak period, is housed in its own mandapam and it matches up to the grandeur and size of the temple. It is a monolithic Nandi weighing about 25 tonnes, and is about 12 feet high and 20 feet long.
