History
The origins of the Swiss Army Fortress Sasso San Gottardo trace back to the late 19th century when Switzerland began fortifying its alpine regions following the opening of the Gotthard railway.
The fortress was part of the broader National Redoubt defense plan developed in the 1880s and significantly expanded during the 1930s and World War II to protect key alpine passes against potential invasions.
General Henri Guisan's defensive strategy during World War II emphasized retreating to and holding the fortified alpine perimeter, with Sasso San Gottardo playing a crucial role.
The fortress continued to have military relevance during the Cold War until many such fortifications were decommissioned in the early 21st century.
Today, it stands preserved as a museum highlighting Switzerland’s unique approach to defense and neutrality.
