Preußenmauer, Defensive wall in Heligoland, Germany.
The Preußenmauer extends along the coastline of Heligoland island, featuring solid stone construction techniques from the early 20th century military engineering.
Built in 1910 during the German Empire expansion period, this wall formed part of the strategic fortification system protecting the North Sea territory.
The wall represents the architectural methods of Prussian military engineers who designed defensive structures throughout the German coastal regions.
Visitors can access the wall structure during daylight hours and walk along its perimeter to observe the North Sea panorama.
The wall remains one of the few preserved military structures from the pre-World War I era on Heligoland island.
