In the middle of the 1930s, a Luftwaffe Fliegerhorst (air base) was built in the north of Werl. After the World War II, the site was used by Belgian units. On a small part in the northwest of the former air base, an airfield for the Belgian army aviation was established. Beside the army aviation, the area was also occupied by other units, among them was a special weapons site of the US Army. After the withdrawal of the troops at the beginning of the 1990s, the site was converted into the KonWerl industrial estate. Individual buildings have been preserved.
