The Retreat will take place on 28^th and 29^th of March 2022 at Schloss Herborn. In 16^th century the historical Herborn castle housed the so-called “Hohe Schule” (Herborn Academy), an insititution of higher learning with four faculties. At the turn of the century the academy moved from Herborn to Siegen into the buildings of the lower castle. As such, Schloss Herborn can be considered a precursor of today’s University of Siegen.
