The fortress trail
Walk at your own pace and learn about the nature, unique architecture and history of the fortress through the centuries. The map of the trail provides information about historical events and famous people, and what everyday life was like within the fortress's thick walls. The map also contains information about the design of the fortress, and explanations of what, to most of us, are unfamiliar words and expressions used about buildings, weapons and other things that were part of fortress life.

Tips for things you can do yourself
Large areas of the fortress are open parkland that you can use for recreation purposes. Visitors can enjoy a picnic, play ball games or just go for a walk in these areas. As long as you show due consideration for the historical surroundings, the only limit is your imagination.
