One of Colombo's more unusual religious structures, the Sambodhi Chaithya is a white Buddhist stupa built on two massive concrete arches that span a road leading to the harbour. The stupa sits about 10 metres above ground level, accessible by steps from the street, with views over the Fort area and the sea. It is an active place of worship, visited daily by devotees who climb the stairs to make offerings.
The stupa is in the Fort district, close to the old lighthouse. Its elevated position means it's also a decent vantage point for looking back at the old Fort buildings and across to the new port development. The architecture is mid-century modern Lankan — a style that combined Buddhist forms with contemporary construction methods in a way unique to post-independence Sri Lanka.
