Due to the presence of a number of barracks built during the 1930s and its location next to the main East-West Autobahn in northern Germany, after World War II Bielefeld became a headquarters town for the fighting command of the British Army of the Rhine – BAOR (the administrative and strategic headquarters were at Rheindahlen near the Dutch border). Until the 1980s there was a large British presence in the barracks housing the headquarters of the British First Corps and support units, as well as schools, NAAFI shops, officers' and sergeants' messes and several estates of married quarters. The British presence was heavily scaled back after the reunification of Germany and most of the infrastructure has disappeared.
