History.
Spinola Redoubt built in 1715–1716 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. 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.
The redoubt has been demolished and its site is now a public garden.
