If you are a culture buff, then Richmond Castle should not be overlooked. Exploring the place is amongst the top things to do in Kalutara; as it is a fine amalgamation of British and local architectural styles. Built in 1896, shiploads of Burmese teak were brought over for the construction of the fabulous mansion, for which its wealthy owner, a Sri Lankan aristocrat, spared no expenses. The place is made up of stables, staff rooms, guard's quarters, a huge ballroom for dancing and many other elegant and luxurious trappings associated with the wealthy. Enjoy exploring the 42 acre estate, and building complete with stained glass windows elaborately carved wooden features and grand rooms.
