Richmond Castle was once the mansion of N. R. A. D. Arthur De Silva Wijeysinghe Siriwardena, a local mudaliyar who was the son of a wealthy planter. During the time he schooled in Britain, he made friends with a Maharaja, and the mansion was said to be inspired by the latter person's castle. Many of the material that was used to build this castle were imported from abroad and only lime and granite were sourced from the local market. Richmond Castle, which is located approximately 7.2 kilometres from properties like Mermaid Hotel & Club, is hailed as one example that reflects the local heritage.
