Burg Meersburg Lake Constance

Looking across Lake Constance from its lofty perch, Burg Meersburg is an archetypal medieval stronghold, complete with keep, drawbridge, knights’ hall and dungeons. Founded by Merovingian king Dagobert I in the 7th century, the fortress is among Germany’s oldest, no mean feat in a country with a lot of old castles. The bishops of Konstanz used it as a summer residence between 1268 and 1803.
