This surprisingly interesting museum includes the house where respected Sinhalese author Martin Wickramasinghe (1890–1976) was born. The exhibits are well displayed, with information in English. Among them is a good section on dance (including costumes and instruments), puppets, kolam (masked dance-drama) masks (including one of a very sunburnt British officer), kitchen utensils and carriages. Don't miss the kitchen goods, including the multipurpose 'mill stone'. Look for the turn near the 131km marker, across from the Fortress Hotel.
The bookshop sells Wickramasinghe's works, which are lauded for their exploration of local cultures and the roots of all the people on the island.
