Fenestrelle Fort

Fenestrelle Fort is a large alpine fortress complex in Piedmont’s Val Chisone, built to defend the approaches through the western Alps. Construction and enlargement took place primarily under the House of Savoy from the 18th into the 19th century.

The complex stretches for nearly 3 kilometres along the ridge and links several forts and batteries by long stone stairways and covered galleries, creating an extensive defensive line. Visitors explore long staircases, terraces and restored barrack blocks and can walk sections of the ramparts for panoramic mountain views.

The fort was erected as part of the Savoyard defensive system and was modified over successive campaigns of military engineering through the 18th and 19th centuries. It later served as a garrison and, at times, a military detention site before partial abandonment and subsequent restoration in the 20th and 21st centuries.

Fenestrelle sits above the town of Fenestrelle in Val Chisone in the Cottian Alps, roughly within the mountainous area west of Turin in northwestern Italy.

• Best time to photograph: Best light for photography is late afternoon when the long ramparts and stairways cast deep shadows along the stonework.
• Scale and nickname: The site is often described as one of Europe's largest alpine fortifications and is commonly nicknamed the "Great Wall of the Alps."
