Sparrenberg Castle

Sparrenberg Castle (Sparrenburg) is a hilltop fortress in Bielefeld, North Rhine-Westphalia, Germany, originating in the medieval period. It sits on a prominent ridge above the city and is a major local landmark.

Visitors can climb the tower for panoramic views over Bielefeld and walk the restored ramparts and terraces that surround the fortress. Guided visits commonly include the casemates and underground passages that formed part of the site’s defensive infrastructure.
