Adhimooleswarar temple complex has two prakarams (outer courtyard) and a small five-tiered rajagopuram (gateway tower). The central shrine faces east and holds the image of Adhimooleswarar (Shiva) in the form of a granite lingam. The granite images of the deities Ganesha (son of Shiva and god of wisdom), Murugan (son of Shiva and god of war), Nandi (the bull and vehicle of Shiva) and Navagraha (nine planetary deities) are located in the hall leading to the sanctum. The hall leading to the sanctum also has the South facing shrine of Nithyakalyani (Parvati), the consort of Adhimooleswarar, in standing posture. As in other Shiva temples of Tamil Nadu, the first precinct or the walls around the sanctum have images of Dakshinamurthy (Shiva as the Teacher), Durga (warrior-goddess) and Chandikeswarar (a saint and devotee of Shiva). There are also images of Bhikshatana, Dakshinamurthy sporting a Veena and Vishnu. The first precinct is surrounded by granite walls.
