Spinola Redoubt (mt|Ridott ta' Spinola), also known as Birżebbuġa Redoubt (mt|Ridott ta' Birżebbuġa), 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.[1] It has been demolished.
Spinola 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.[2] The nearest fortifications to Spinola Redoubt were Pinto Battery to the northeast and Birżebbuġa Entrenchments to the south.
Spinola Redoubt was one of four tour-reduits built in Malta, with the other three being Fresnoy Redoubt, Vendôme Tower and Marsalforn Tower. It had a square shape, similar to the surviving Vendôme Tower.[3]
The redoubt has been demolished and its site is now a public garden.
