Info from Wikipedia
Batschkapp (Hessian dialect for 'flat cap') is a rock and pop concert venue in Frankfurt am Main.
Batschkapp was founded in 1976 to establish an autonomous and left-wing counter culture, and opened on 11 December 1976. It began as a cultural centre associated with the neighbourhood centre Arbeiterselbsthilfe which was located in the inn "Zum Elfmeter", in Maybachstraße next to Frankfurt Eschersheim station.
Batschkapp moved on 10 December 2013. The original venue was demolished in February 2016, after archaeological excavations were made because the site was within the grounds of Rühl'sche Hof, to enable the building of flats and a supermarket.

Location on map is approximate as original location building (where the specified gig took place) no longer exists.
