The Cavallino-Treporti peninsula is well known for its long Adriatic beaches and easy ferry connections to Venice. But on its lagoon-side interior is a network of 19th and early 20th-century military fortifications.
Forte Treporti is one of them and should not be missed.
Come and discover Forte Treporti
Forte Treporti, widely known by locals as Forte Vecchio Cavallino Treporti, is one of the most significant military heritage sites on the northern Adriatic coast.
It’s near Lio Grando, on the lagoon side of the peninsula, about 3 km north of Punta Sabbioni.
History of Forte Vecchio in Cavallino Treporti
Before the Austrians arrived, a French fort already occupied the same position. When Austria took control of the Veneto region in the early 19th century, they recognised the site’s importance immediately.
Whoever held the mouth of the Punta Sabbioni inlet controlled one of the key water entrances into the Venetian Lagoon.
Construction of the current Forte Cavallino Treporti began in 1845 and was completed in 1851. The Austrians built it on the ruins of the earlier French fort, using a combination of red brick and white Istrian stone.
After the Second World War, the fort’s military role ended for good. For a period, it was used as a refuge for evacuees and displaced civilians.
Today, parts of the structure are inhabited by families, and several local cultural and sports associations operate from within the walls. It is not a museum in the formal sense, but it is part of the Via dei Forti route, and its exterior is accessible and well worth seeing.
Military architecture and the Via dei Forti route
Forte Treporti earned Cavallino-Treporti the informal title of “open-air museum.” The Via dei Forti project, developed to protect and promote this heritage, maps out a route connecting all the major fortifications across the peninsula.
- Forte Treporti (Forte Vecchio): the 19th-century Austrian fort at Lio Grando
- Batteria Vettor Pisani: built between 1909 and 1912, this is the main active museum on the route, with a permanent collection covering the Great War, trigonometry on the coastline, and medical care in wartime; admission is €10 for adults and €5 for children aged 6 to 17
- Batteria Amalfi, San Marco and Radaelli: three coastal batteries built in the early 1900s, active during the Austro-Hungarian offensive of 1918
- Fourteen telemetric towers: scattered across the peninsula, dating from after the defeat at Caporetto in 1917, used to calculate artillery distances by triangulation
- Caserma Il Mandracio: the first barracks built in Cavallino-Treporti, constructed in 1911, now a private building
- Caserma Ca’ Pasquali: also built in 1911, notable for a telemetric tower incorporated into its centre
- Second World War bunkers: several surviving anti-aircraft and anti-landing structures built by the German military; most were destroyed at the end of the war, but a handful remain

From Lio Grando, you are also within easy reach of Lio Piccolo, the protected lagoon village a few kilometres further along the same route. The two make a natural pairing for a day away from the beach. The cycle path between them is flat, and passes through some of the most scenic parts of the northern Venetian Lagoon.
Exploring the coastal fortifications of the lagoon
Most people associate this stretch of the Venetian Lagoon with beaches and camping villages, but the fortifications tell another story.

| Batteria Vettor Pisani (museum) | 1909 to 1912 | Paid entry, guided | 1.5 to 2 hrs |

Tips for cycling to the historic forts
The whole Via dei Forti route is designed for biking.
The terrain is flat, the paths are well-maintained, and the distances are manageable even for families with children.
As the Cavallino-Treporti coastline sits right at the edge of the route, you can easily combine a morning on the fortification circuit with an afternoon on the beach.
What to pack for the day
- Water (at least 1.5 litres per person in summer)
- Sun cream and a hat; the lagoon-side paths have little shade
- A light waterproof if visiting in spring or autumn
- Insect repellent for early morning or late afternoon riding near the lagoon
- A printed or downloaded map of the Via dei Forti route
- Cash for the Batteria Vettor Pisani entry fee
If you are travelling with younger children, the full route may be too much for a single day. In that case, ride directly to Fort Treporti from Treporti village (around 4 to 5 km), explore the village and return via the lagoon paths.
