I am very surprised and impressed by the size of Wilhelmsburg, Fort XII; I hadn't expected that. The 200 m x 130 m castle was built between 1842 and 1849 as the centerpiece of the Ulm Federal Fortress. The citadel could accommodate 6,951 men, and the inner courtyard covers 1.3 hectares. The history of its post-military use is also interesting. Everything is well documented on site.

The Ulm Fortress Trail initially leads through the spacious grounds of the Wilhelmsburg. The construction site at Prittwitzstrasse/KönigWilhelm-Turm can be bypassed on a narrow (but sometimes slippery) path.

Location: Corner spur at the confluence of the Lone and the Hürbe. Altitude: 513m at the highest point. 498m in the courtyard. 480m in the Lone valley. Size and scope: 3996m2 and 300m ring wall. The Kaltenburg stands on a mountain spur above the Hürbe and Lone valleys. The three round towers still visible date from the Wilhelminian period, the two corner towers from the 17th century. First mentioned in 1240. The castle complex has been gradually renovated for several years. It's always worth a visit and the view is great.

The back part of the fort is particularly exciting. There you can walk around the old battlements. But be careful, nothing is lit or secured there. Access at your own risk.

You can visit the ruins, some of which are currently being restored, and you can even go up to the tower for a donation.
