 Tegart's Wall

Tegart's Wall was a barbed wire fence erected in May-June 1938 by British Mandatory authorities in the Upper Galilee near the northern border of the territory in order to keep militants from infiltrating from French-controlled Mandatory Lebanon and Syria to join the 1936–1939 Arab revolt in Palestine.With time the security system further included police forts, smaller pillbox-type fortified positions, and mounted police squads patrolling along it.
