Forte di San Marco, Military fort in Caprino Veronese, Italy.

Forte di San Marco is a military fort in the hills of Caprino Veronese, constructed with local red ammonitic stone and terracotta arches. The structure features two internal courtyards, multiple artillery positions, and a prominent tower with firing positions at different levels.

The fort was built between 1888 and 1913 by the Italian Royal Army as part of the defensive line along the border with Austria-Hungary. The project followed General Enrico Rocchi's military engineering principles, drawing from Prussian fortification models.

The fort's name comes from Monte San Marco, the hill on which it stands above the Ceraino gap. Its plan had to bend around the rocky ground, so the rectangle is irregular. The masonry is dressed blocks of red ammonitic stone from the Lubiara quarries, while the arches are terracotta.

The fort stands at 451 m on a southern spur of Monte Cordespino, above the start of the Chiusa di Ceraino, in the Lubiara locality of Caprino Veronese. It is privately owned and partly abandoned, so surfaces inside are uneven. A rock-cut ditch 5 to 6 m wide runs around the walls except on the valley side, where the ground drops away.

The fort never saw combat in World War I: its guns fired only a few shots at Austrian aircraft heading to bomb Verona, and the garrison of 300 soldiers used it mainly as barracks and depot. Today a soft air club from Verona plays in the courtyards.
