Fort Berge, Military fortress in Magdeburg, Germany.

Fort Berge was a four-pointed star fort built from 1721 under Gerhard Cornelius Walrave, pushed far south of Magdeburg's main ramparts. Inside the main wall ran a vaulted three-storey barracks; beyond it lay a moat, a smaller outwork called the Enveloppe, a second moat and a sloping glacis. Access was through Walrave's Sterntor. It was demolished in 1904 for housing and commercial buildings.

Construction began in 1721 under Gerhard Cornelius Walrave and took its name from a nearby monastery. The fortification shaped Magdeburg's military and urban development for nearly 180 years.

The name Berge came from the nearby Kloster Berge, a monastery a short distance to the south; the star shape gave the site its second name, Stern. Today the Sterngelände housing area, Sternstraße and Sternbrücke keep both names alive, and the Sterntor, rebuilt from 2008 at the Domplatz, is the one surviving piece of the fort.

Nothing of the fort itself survives; the site lies south of the old town, now built over with early 20th-century houses and shops on the so-called Sterngelände. The Sterntor, Walrave's gate, was rebuilt from 2008 at Magdeburg Cathedral Square, so look for it there rather than at the original fort location.

The architect Walrave later became a prisoner within the structure he had designed and was given a specific area for his movement inside. This surprising turn shows the complex history of the site and its use across different periods.
