Burg Glauburg, Medieval castle ruins on Glauberg hill, Germany

Burg Glauburg is a medieval castle ruin sitting on a basalt ridge in the Wetterau region. The remaining walls show defensive structures, basement rooms, and a ground level with a Romanesque arch.

A Frankish large fortress stood on the Glauberg in the 7th to 9th centuries; in the 12th and 13th centuries the site was absorbed into the Staufen castle system of the Wetterau, when a tower-like building with a Romanesque stone arch was raised at the wall. The Frankfurt patrician family Glauburg held its ancestral seat here, documented from 1247 together with the lords of Düdelsheim and other joint owners. The castle was probably destroyed as early as 1256, ending settlement of the plateau.

The name comes from the families who lived here in the past. Today you can see traces of how residents built homes attached to the inner walls and used this space daily.

Visitors can explore a reconstructed gate structure and see a five-meter-deep cistern that collected rainwater for inhabitants. The hill offers walking paths with open access to the grounds.

The foundations of an entire row of houses on the northern side reveal that a large settlement thrived here, not just a fortress. Excavations have uncovered many residential cellars that show how much ordinary daily life happened within these walls.
