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.

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.

Fort Albeck was built on Saffronberg between 1846 and 1859. There was room for a maximum of 1,340 soldiers. It is the largest external fort of the Ulm federal fortress complex.

Illerkirchberg is rich in history, featuring sites from different eras. It's home to Kastell Unterkirchberg, an early Roman border fort that was part of the Danube Limes, established around 40/45 AD. Dominating the landscape is the Fugger Castle Oberkirchberg, a medieval hilltop castle acquired by Jakob Fugger 'the Rich' in 1507, reflecting centuries of aristocratic and economic power. The area also includes 19th-century federal fortresses like Wilhelmsburg, part of the extensive Ulm Federal Fortress.
Fugger Castle Oberkirchberg is a prominent landmark and remains private property. While it's not open for interior visits or event rentals, its impressive structure and historical significance can be appreciated from its exterior, offering a glimpse into the legacy of the influential Fugger family.
Kastell Unterkirchberg was an early Roman border fort, part of the Danube Limes, and the largest Roman auxiliary fort on the upper Danube Limes.
