Once upon a time Den Bosch boasted over four miles of defensive walls. Wind mills, cannons and sturdy towers were all part and parcel of these historic bastions. Despite the fact that most of them have disappeared, the city is still proud of its architectural and military past. One of the best spots to see and experience this rich history is the Bastionder where you can see a lovely city park with possibly the best view of Den Bosch over the Bossche Broek. The last part of the fortifications were added to the fortress (Bastion Oranje) in 1634. In the spring thousands of crocuses are in bloom, in summer you can have a picnic underneath its ancient trees and in the autumn this rustic oasis is a great place for a walk. The underground information centre offers visitors information about the military history of the city across the centuries. Unfortunately, the building isn't always accessible. You can only visit it as a part of a city walking tour or a boat trip on the Dommel.
