Qalet Marku Redoubt () was a redoubt in the limits of Naxxar, Malta. It was built in 1715–1716 by the Order of Saint John as one of a series of coastal fortifications around the Maltese Islands. It was demolished to make way for the coast road, but its remains are possibly still buried under the road. Read more on Wikipedia
