Graben

Graben is a castle ruin in Obernburg am Main situated on elevated terrain with remaining stone walls displaying medieval masonry and fortification elements. The preserved sections reveal construction methods from centuries past and how the structure once defended against attack.

The structure was built when regional lords expanded their territories and needed a strong position along Main River trade routes. The castle underwent several modifications across different periods as its owners added and altered sections to meet changing defense needs.

The castle once symbolized local power and shaped the identity of the area around it. Visitors today can sense how central this fortress was to the community that built and maintained it.

Marked paths lead from Obernburg am Main's town center to the ruins, and information panels explain different sections of the site. Wearing sturdy shoes is advisable since the ground is uneven and some paths become steep in places.

The ruins clearly display evidence of at least two distinct construction periods, with newer stonework visible alongside older walls. This layering of building phases tells the story of how the fortification was repeatedly adapted as circumstances changed across the centuries.
