Bridge House is a complex of buildings at the harbour mouth in Castletown, developed by the Quayle family from the third quarter of the eighteenth century. The home of George Quayle (1757-1835), politician, banker, and inventor, it houses the boathouse and dock he constructed for the yacht Peggy, and was opened as the Nautical Museum in 1951. The Bridge House Papers, deposited in the Manx Museum, are a significant archival collection relating to the Island's governance and estate administration.
