The presiding deity Siva is installed in the form of Lingam in the sanctum sanctorum. The Siva temple's architectural details conform to what is written down in the Hindu scriptures known as agamas. The Siva temple faces east and has three pathways around it. A sacred pond is situated in front of the Siva temple and a fig tree stands by the side of it. The main sanctum and the structure above the sanctum are one of the largest in Sri Lanka.
