Werk Glockenberg, Prussian fortification in Asterstein district, Koblenz, Germany.
Werk Glockenberg was a Prussian fortification in the Asterstein district with a three-winged, two-story tower structure built south of Fort Asterstein as part of the defense system for Pfaffendorfer Höhe. The preserved Teufelstreppe staircase still connects the district to the city center today and is carved into stone.
The fortification was built in 1822 as part of expanding Koblenz's defense system under King Friedrich Wilhelm III. It was partially demolished in the 1920s, but underground cellars from the original 1864 structure remained beneath modern buildings.
The place is part of the UNESCO World Heritage Upper Middle Rhine Valley and the Teufelstreppe staircase is used daily by locals and visitors alike. The stone steps connect two neighborhoods and form an important part of how people move through the city.
The Teufelstreppe is easy to reach on foot and offers a direct route between Asterstein and the city center for walkers. The climb up the stone steps requires some effort, but it is manageable for most visitors.
Underground cellars beneath modern buildings preserve parts of the original military construction and show how the old fortification still exists within the new city. Visitors often walk over these hidden layers without knowing that traces of the past remain underneath.
