A bartizan or guerite is an overhanging, wall-mounted turret projecting from the walls of medieval fortifications from the early 14th century up to the 16th century. Most frequently found at corners, they protected a warder and enabled him to see his surroundings. Bartizans generally are furnished with oylets or arrow slits.1 The turret was usually supported by stepped masonry corbels and could be round or square.23
A British concrete position (Bartizan style), built at the North-Western corner of Sergei courtyard, Jerusalem. This is probably the sole existing testimony of the British "Bevingrad" constructed in 1946.
