Forte Manin
Forte Manin, also known as Forte Marghera, stands on former marshland beside the Venetian lagoon, near Mestre and Venice. Its pentagonal core has four bastions, a double moat, and three outer lunettes beyond the main structure. The Canal Salso connects those defensive waters with the lagoon and once supported movement between Mestre and Venice.
Construction began in 1805, after the Treaty of Campoformio placed this mainland position within reach of Venice. French architect Marescò later added six outer bastions, a double moat, and two side forts. Only star-shaped Fort Campalto was built, while the fortress itself served French, Austrian, and Italian military forces. In 1849, about 2,500 patriots defended the works during a long Austrian siege before withdrawing towards Venice.
Two French-period barracks face Mestre, built from Istrian stone with bomb-proof roofs for 150 to 200 soldiers each. Nearby, French and Austrian powder magazines retain their barrel-vaulted roofs, while an oval dock opens towards Venice. The former fortress now forms a public park owned by the City of Venice, with cultural events among its canals, earthworks, and military buildings.
