Fortifikation Hauenstein, Military fortification system in Basel-Landschaft and Solothurn, Switzerland
The defensive line spans 42 kilometers in a semi-circle configuration around the railway center of Olten, reaching elevations of 1,100 meters above sea level.
During World War I from 1914 to 1918, this fortification system served as a primary defensive position for the Swiss Army, designed to protect against potential invasions.
The Hauenstein Fortification Memorial Path features twelve information panels that present the military heritage and construction methods of this extensive defense network.
Visitors can access the fortification remains through marked hiking trails starting from Langenbruck, with dedicated parking areas and information points along the route.
The fortification complex incorporated 500 military structures designed to accommodate 45,000 soldiers and 6,500 horses during wartime operations.
