One of the primary attractions is, undoubtedly, the Kalutara Temple which was built during the 20th century. Also known as the Gangatilaka Vihara, the Temple is built on rock overlooking the Kalu Ganga. Those travelling from Colombo towards Kalutara on the Galle Road will be able to see the three storey dagoba, which is believed to be the only hollow Stupa in the world, as they traverse the long bridges over the River.
Opposite the Kalutara Vihara Dagoba is the Kalutara Bodhiya that is venerated by Buddhists in the island. While the Bo Tree assumes immense religious importance in providing shade to Lord Buddha as he attained Enlightenment, the Kalutara Bodhiya is one of thirty two samplings of the venerated Bo Tree in Anuradhapura, which in turn is a sampling of the Bo Tree under which the Lord Buddha attained Enlightenment. Another Temple that tourists can visit is the Asokarama Buddhist Temple which was built during the 19th century.
