Located about 15 kilometres from the Neptune Ayurveda resort, this temple is held in veneration by most Buddhists. (part of sentence removed here as it's repeated below) It is said to be one of the 32 places indicated by Arahath Mahinda Thera to King Devanampiya Tissa in the second century BCE as a place where one of the sacred Sri Maha Bodhi saplings should be planted. The temple remained largely intact until the European invasions.

The Portuguese destroyed the temple and built a fort on the site. The Dutch took it over and later a British agent converted it into his residence during the colonial era. The modern temple, built in the 1960s, is located just south of the Kalutara Bridge and is the only dagoba (Buddhist shrine) in the world that is hollow. Inside, the cool echoing walls are lined with a sequence of 74 murals depicting various scenes from the Buddhist Jataka (the 550 previous births of the Buddha to be - Bodhisattva) tales. The remainder of the temple buildings are situated in a compound on the other side of the road, featuring unusual Bo Tree enclosures and Buddha shrines. It's a lively complex, and a good place to watch the daily rituals of Sri Lankan Buddhism: the offerings to the Buddha images are made three times a day. Devotees place food and flowers in front of the images, lighting coconut-oil lamps, tying prayers written on scraps of cloth to one of the Bo trees or pouring water into conduits which run down to water the Bo tree's roots. Outside, a sequence of donation boxes line the roadside, popular with local motorists, who frequently stop here to offer a few coins and say a prayer for a safe journey.
