• Our tours and exhibitions are not appropriate for children under 7 years of age. We regret that we must therefore refuse entry to children in this age group. This is due to the Jugendschutzgesetz (JuSchG) § 8 (German Child Protection Law). Due to the difficult historical themes discussed during our tours, it is the responsibility of the parent or guardian to decide whether children between 7 and 13 years of age may take part. The delivery and content of our tours is aimed at adults, and can only be recommended for children aged 14 years or older.
