This unique museum was originally the 17th-century residence of the Dutch governor and has since been used as a Catholic seminary, a military hospital, a police station and a post office. The mansion contains a lovely garden courtyard and has a nice faded feel since a 1977 restoration. Exhibits include Dutch colonial furniture and other artefacts.
It's here in 1638 that King Rajasinghe II of the Kingdom of Kandy signed the treaty that opened up Ceylon to the Dutch.
