The temple's architecture demonstrates an eclectic mix of Sri Lankan, Thai, Indian, and Chinese architecture. This Buddhist temple includes several imposing buildings and is situated not far from the placid waters of Beira Lake on a plot of land that was originally a small hermitage on a piece of marshy land. It has the main features of a Vihara (temple) , the Cetiya (Pagada) the Bodhitree, the Vihara Mandiraya, the Seema malaka (assembly hall for monks) and the Relic Chamber. In addition, a museum, a library, a residential hall, a three storeyed Pirivena, educational halls and an alms hall are also on the premises. Most notable for tourists is the architecture of the Simamalaka Shrine, which was built with donations from a Muslim sponsor to the design of Geoffrey Bawa.
