The north wing houses the local history museum, which is well worth a visit and showcases 18th and 19th century Berg domestic culture and typical Berg crafts. Medieval history is documented with documents and seals of the great counts and lords of the castle. Various historical films are shown on a modern video wall. The museum is currently closed as it is being renovated over the next few years. However, the videos that are shown there can also be viewed online: YouTube.
In addition to the historic fountain, the castle garden with its historic pavilion has also been preserved.
In addition to a visit to the castle, a tour of the historic old town is also worthwhile.
