Preußenmauer

The Preußenmauer is a coastal fortification on Helgoland island built from solid stone in the early 20th century. The structure runs along the shoreline and displays the engineering techniques typical of that military construction period.

The wall was built in 1910 during German imperial expansion and served as part of a coastal defense network. It belonged to a system of fortifications meant to protect the North Sea region.

The wall shows how Prussian military engineers built coastal defenses using consistent methods across German territory. Visitors can still see their craftsmanship in the solid stonework and sturdy design.

The structure is accessible during daylight hours and you can walk along it while viewing the North Sea coast. The best visit depends on weather conditions, so visitors should pay attention to wind strength and tidal times.

The wall is one of the few remaining military structures from before World War I on the island. Today visitors can see how the sea has shaped the structure over generations and what marks the elements have left on it.
