Forte Mezzacapo — the Concrete Fort of the Mestre Entrenched Camp

Built to stop an army on the road to Treviso, this fort never fired in anger: its guns were taken away in the summer of 1915. Today its vaults hold exhibitions instead of shells.

At a glance

Forte Carlo Mezzacapo, also called the forte alla Gatta after the locality, stands at Zelarino on the Venetian mainland, in Via Scaramuzza. It was built in concrete between 1909 and 1912 to strengthen the campo trincerato of Mestre, the ring of forts that defended Venice from the land side. Its task was to control the road to Treviso and the railway to Udine.

History

The fort is named after General Carlo Mezzacapo. It belongs to the second generation of forts around Mestre, built in reinforced concrete when the older brick works of the entrenched camp no longer answered to new artillery. Its guns sat under steel cupolas.

The fort had hardly been finished when the First World War showed that works of this kind were of no use, and in July 1915 it was disarmed. It was turned into a powder magazine and a depot for munitions and materials. Since 2004 the association Dalla guerra alla pace has held cultural and historical events there, and the fort is today a cultural centre.

What you see
