Fenestrelle Fortress
Valle d'Aosta
Fenestrelle Fortress, located in the Piedmont region of northern Italy, is the largest alpine fortification in Europe, spanning 130 hectares. Constructed between 1728 and 1850 under architect Ignazio Bertola, it was designed to protect the access to Turin via the Chisone valley. The fortress complex includes a unique 3-kilometer long wall and an indoor staircase of nearly 4,000 steps, which is unparalleled in Europe. Historically, it served as a strategic military defense point, changing hands between French and Savoy forces, and later functioned as a prison for political detainees, including notable figures such as Joseph de Maistre and supporters of Giuseppe Mazzini. After periods of abandonment following World War II, restoration efforts began in the 1990s, revitalizing the site as a cultural and tourist destination. Today, Fenestrelle Fortress stands as a symbol of the Metropolitan City of Turin and is recognized by the World Monuments Fund as one of the world's most important archaeological sites at risk. Its vast scale, architectural uniqueness, and historical significance make it a captivating destination for visitors interested in military history and alpine heritage.

The original Fort Mutin was built in 1694 but was captured by Victor Amadeus II's troops in 1708 during the War of the Spanish Succession.
Following the Treaty of Utrecht in 1713, the territory was ceded to the Duchy of Savoy, which commissioned Ignazio Bertola to design a comprehensive fortification system.
Construction began in 1728 and was completed in stages until 1850.
The fortress served various military roles, including as a prison during Napoleonic times and the Kingdom of Sardinia era.
