Fort of Komiža

Fort of Komiža (Croatian: Kaštel, also known as the Komuna) is a Venetian defensive tower standing right on the waterfront of Komiža, a fishing town on the island of Vis. The stout stone fortress, now one of the town's landmarks, recalls an era when Vis was the most exposed and most frequently raided outpost of central Dalmatia.

Why was the fort built?

Komiža sat more exposed to the open sea than any other Dalmatian settlement, making it a recurring target for Ottoman raiding fleets and pirates. The Venetian authorities were reluctant to cover the full cost of coastal fortifications, so local fishermen stepped in to fund much of the work themselves. An inscription dated 1592 on the north wall records that money to finish the building was raised by the crew of one of the fishing grounds south of the island of Biševo. Construction was completed in 1595 under Prince Ivan Grimani of Hvar, whose coat of arms and a cross are carved above the entrance.

How has the building changed over time?

The Kaštel originally stood almost directly at the waterline — holes for mooring ropes are still visible in the walls today. A well was cut inside during the 17th century, and a tower section was added in the 19th century, after which the fortress lost its military purpose and became a public communal building, which is why locals still call it the Komuna. This layered history, from bastion to cistern to town office, makes the fort a small physical timeline of Komiža itself.

What will you see inside?

The old fortress now houses the Fishing Museum, dedicated to the maritime trade that sustained the town for centuries. Exhibits include historic nets, hooks, fishing lanterns, and archival photographs of harbor life. A particular highlight is the replica of a gajeta falkuša, the traditional Komiža fishing boat that once formed the backbone of the local fleet and remains one of the town's proudest symbols.

How do you get there?

The fort sits directly on Komiža's harborfront, so it's impossible to miss on a walk along the promenade — it's usually the first thing that catches the eye when arriving by sea. Komiža lies on the western side of the island of Vis, and the island itself is best reached by ferry or catamaran from Split.

When is the best time to visit?

Summer is the liveliest season, when the harbor is at its busiest and a stroll past the fort pairs naturally with a swim and a meal of fresh fish at one of the nearby konobas. The thick stone walls also offer welcome shade during the hottest hours, making the fort a pleasant stop while exploring the old town.
