Project Riese

Seven extensive underground tunnels spread across multiple locations form a vast network of partially completed chambers and corridors beneath the mountains.

Between 1943 and 1945, Nazi Germany initiated this construction using forced labor from concentration camps, resulting in thousands of deaths.

The underground passages contain exhibitions about wartime technology, including full-scale models of V1 and V2 weapons from World War II.

Visitors need warm clothing as the tunnels maintain a constant temperature of 5°C and high humidity throughout the year.

The purpose of this massive construction remains unknown, with theories ranging from Hitler's headquarters to nuclear weapons development facilities.
