The Federal Ministry of Defense has identified several former military sites (were to be converted to city use) for the new military service program.
Four of those....former German Army sites: Graf Stauffenberg Barracks in Sigmaringen (Baden-Württemberg), Unteroffizier Krüger Barracks in Kusel and the Kurpfalz Barracks in Speyer (both Rhineland-Palatinate), Kanaal van Wessem Barracks in Soest (North Rhine-Westphalia).
Fifth? Former US Army site: Ray Barracks in Friedberg (Hesse). This will include Ockstadt....the training area for Friedberg. Location? About 20 miles north of Frankfurt.
Closure? I looked it up.....August 2007....so almost 20 years.
Best I can see....various plans of re-use kept coming up and Friedberg never getting funded/approved.
Trigger for the five re-use concepts? The Bundeswehr says they are going to 'grow'. If you asked me on the current shape of buildings at Ray? I'd say all of them require renovation, and you'd be looking at six to ten years before it was fully operational.
