Tagliata della Scala, Military fort in Valbrenta, Italy.

Tagliata della Scala is a military fort built into the mountainside in the Valbrenta area, featuring multiple levels linked by underground corridors and covered passages. The structure includes firing positions, barracks areas, and fortified galleries designed to control the valley routes below.

Built between 1892 and 1904 as part of the Brenta-Cismon barrage, shortly after Primolano was annexed to the Kingdom of Italy; the Savoy coat of arms is still visible on the entrance portal. The garrison abandoned it on 12 November 1917 after Caporetto, and Austrian troops of the 1st Mountain Brigade occupied it the next day. Before leaving, the Italians blew up the ammunition depots, leaving two large breaches still visible in the walls.

The Savoy coat of arms is still visible on the entrance portal, a sign of the fort's construction shortly after Primolano joined the Kingdom of Italy. The fort belonged to the Brenta-Cismon barrier, built to control the main route between Valsugana, Feltre and Primiero. Its long covered gallery, a caponnière, barred the road over a long distance and connected with the Fontanelle fort.

Wear sturdy footwear for navigating steep stairs and uneven ground throughout the fort. Plan to spend time exploring the multiple levels, as the layout can be confusing without taking a careful route through the passages.

A long underground staircase with more than 200 steps links two sections of the fort while including firing positions along its path. This hidden internal passage shows how soldiers could move quickly between strategic positions without exposure.
