From 2010, the Alfred Toepfer Stiftung F.V.S. foundation has made the Seminarzentrum Gut Siggen in Holstein, owned by the foundation, available to the HFBK Hamburg for 12 days a year free of charge for seminars and group excursions.

The Seminarzentrum is in a quiet and secluded location, 20 km east of Oldenburg in Holstein and 70 km from Lübeck and Kiel. It is a 15 minutes' walk away from the Baltic coast. More information can be viewed at www.toepfer-fvs.de/siggen.html
