The Saracen Tower in Beaufort, Nord, in the Hauts-de-France region, is a ruined medieval fortification and protected historic monument. The square tower was erected in 1173 by Baudouin V, Count of Hainaut, as a defensive work intended to counter his rebellious vassal, Jacques d'Avesnes. Today only the lower vaulted hall and fragments of the upper storey walls survive. The ruin stands behind the Hospital Farm, which dates from 1844, on private land without public access. - AsNotedIn
