Coordinates: 49°23′12″N 8°41′03″E / 49.3867°N 8.6842°E Campbell Barracks, in Heidelberg, Germany, was the location of the Headquarters of the United States Army in Europe and Seventh Army (HQ USAREUR/7A), as well as V Corps and the headquarters of NATO’s Component Command-Land Headquarters, Heidelberg.
As part of the Nazi military buildup, the German 110th Infantry Regiment was activated in May 1936 and stationed in Heidelberg. The existing Grenadier-Kaserne (now Patton Barracks) was not large enough for the regiment. Accordingly, a new installation was built in 1937 on what was then farmland on the southern outskirts of Heidelberg near the suburb of Rohrbach.
At first unnamed, the new installation was designated Großdeutschland-Kaserne after Austria became part of the German Empire in March 1938. Stories linking Großdeutschland-Kaserne to the Großdeutschland Division of World War II have no foundation. The casern predates the division, which was not formed until May 1942. Neither the division nor any of its subordinate units were ever stationed in Heidelberg, nor was the 110th Infantry Regiment ever attached to the Großdeutschland-Division.
When completed, the new Heidelberg barracks became the home of the 110th Infantry's headquarters, its 1st Battalion and its two regimental support companies. The regiment's 2d Battalion was stationed at Loretto-Kaserne (now called Hammonds Barracks) in Seckenheim and the 3d Battalion at Grenadier-Kaserne. The Keyes Building on Campbell originally served as the regimental officers mess.
