Versäumte Portraits

Small multicache with two stations (start and final station) in Bonn city center. Attention: Depending on the day of the week and time of day, there may be a lot of muggles! The cache container does not contain a pen!

However, the cache can only be solved during the opening hours of the University Museum (Wednesdays to Sundays from 12:00 to 17:00, the museum is closed on public holidays). The exhibition can be visited from April 10 up to and including July 31, 2025.
