It was built in the early 1800s.
During the events of 1848-49 it was armed with twelve cannons, of which two 18, two 12, and six 6 and a 6 howitzer.
It was built by the French (with the name of Forte Eau) at the same time as Forte Marghera (it was considered an accessory work). In 1849 the commander of the fort was the artillery captain Andreasi, an excellent young and courageous man. On 15 August 1848 the Austrians fired against Marghera and Fort Eau with the usual field pieces and always from afar.
On May 18, 1849, an Austrian column moved against Fort Manin, but its defenders, equipped with weapons, came across their path and, protected by the fort's cannon, forced it to retreat. On the 19th and 20th, the besiegers began a lively musket fire against the outposts.
Also in May 1849 the Austrians built batteries on the other end of the mainland, to the right of the fort, against Fort Manin or that of San Giuliano, and to disturb communication with Venice. Then the Andreasi with thirty artillerymen and some rocket engines made an admirable sortie. He went under the Austrian batteries and, throwing rockets at them, made the enemy withdraw.
After 1849 the Austrians renamed it Fort Gorzhowsky. Until the end of the 19th century it remained armed, then it became just a powder magazine. Nothing remains of the nineteenth-century buildings. Only new reinforced concrete buildings are present. It is now included in the San Giuliano Park project but in the meantime it is in a state of abandonment.
