Kölner Festungsmuseum
Volunteer-run museum in Prussian fortification VIII b — home to Germany's last surviving drawbridge, moat, and sculpture park in Marienburg.
The Kölner Festungsmuseum is a volunteer-run museum, still partly under development, housed in Intermediate Work VIII b. It documents Cologne's Prussian fortifications — a largely forgotten era when over 180 fortress buildings once shaped the city.

History
Intermediate Work VIII b forms the southern left-bank terminus of the outer fortress ring, which ran along Militärringstraße and protected Cologne from attack between 1873 and 1918. Built in 1876 as a Biehlersches Schemafort for Rhine defence, the gorge barracks were reinforced between 1887 and 1891 following the brisance shell crisis. The installation was armed with a long 15-cm ring cannon and three 9-cm C/73 cannons; in wartime, roughly 150 soldiers were stationed here.
A Special Status
Under the Treaty of Versailles, the fort was partly demolished in 1926 — the last in Cologne to be so treated. Unlike other Cologne fortifications, the surrounding moat with its nearly intact counterscarp, the gorge caponier, and the drawbridge all survived, giving the structure its exceptional standing.
Sculpture Park
In 1985, the Kunstraum Fuhrwerkswaage created a sculpture park on the roof and in the moat. The original eight sculptures used primarily steel, concrete, and earth; seven works remain on display outdoors today, including pieces by Ansgar Nierhoff, Lutz Fritsch, and Heinz-Günter Prager.
Renovation and New Exhibition
Following extensive renovation work on the façade and gorge caponier, visits were restricted for over two years. In time for the 150th anniversary of Intermediate Work VIII b, the main work was completed and a newly conceived exhibition on Prussian fortress history is now on show.
Tours and Further Sites
The roughly 90-minute guided tours begin outdoors with the moat, sculpture park, and former rose garden — including a demonstration of the drawbridge — before heading inside from the guardroom to the powder magazine. The operators cover military architecture and local history without glorifying war or weapons. The Institut für Festungsarchitektur also runs three branch locations: Fort VI "Deckstein" in Cologne-Lindenthal, the Winkelturm in Cologne-Niehl, and the tunnel bunker at the Oberlandesgericht Köln.
