Fresnoy Redoubt (Maltese: Ridott ta' Fresnoy), also known as Kalafrana Redoubt (Maltese: Ridott ta' Kalafrana), was a tour-reduit in Birżebbuġa, Malta.
It was built by the Order of Saint John in 1715–1716 as one of a series of coastal fortifications around the Maltese Islands.
Fresnoy Redoubt was built in 1715–1716 as part of a chain of fortifications that defended Marsaxlokk Bay, which also included three other redoubts, the large Saint Lucian Tower, two smaller De Redin towers, seven batteries and three entrenchments.
It had a semi-circular front, and a redan on the landward side, all of which were pierced by musket loopholes.
[3] The limestone-redoubt was demolished by an order given by the Public Works Department on 22 February 1897.
