The Fortino di Sant'Antonio is a small stone fort at the north-eastern tip of Bari Vecchia, the old town of Bari, where the old sea walls turn the corner from the old port towards the modern seafront. It is one of the few surviving pieces of the towers that once guarded the walled city, and the promenade around it is one of the best places in Bari to watch the Adriatic.
The Fortino di Sant'Antonio at a glance
- Where: on the seafront at the eastern edge of Bari Vecchia, where the walk along the old sea walls (the Muraglia) meets the start of the Lungomare.
- Built: as a tower probably in the 15th century; rebuilt in the 16th century when Bari's defences were modernised.
- What it is today: a historic monument used as a venue for events and exhibitions; the outside can be seen at any time.
- Time needed: 15–20 minutes, or longer if you walk the sea walls or wait for sunset.
From watchtower to fort
In the late Middle Ages Bari was ringed by walls with several large towers, and the Torre di Sant'Antonio, named after St Anthony the Abbot, guarded the old town's corner on the sea. Accounts describe it as a small castle with its own commander and garrison. Most sources date it to the 15th century, though its core may be older.
The original tower did not survive. It was rebuilt in the 16th century as part of the works to update the city's fortifications under Isabella of Aragon, Duchess of Bari, at a time when walls had to stand up to artillery rather than arrows. Later, as the city grew beyond its walls and the seafront was redeveloped, the fort lost its military role. Today it is one of only two survivors of those great towers of the walled city, and it is used for cultural events.
What to look for
- The solid stone mass of the fort: low, thick walls built to defend the corner of the old town from the sea.
- Its position: stand on the promenade and you can see how the fort covers both the old port side and the open sea.
- The Muraglia: the stretch of old sea wall that runs from the fort along the edge of Bari Vecchia, now a raised walkway.
- The colour of the stone: the pale local limestone, typical of Bari Vecchia, looks warm and golden when the sun is low.
- The view along the Lungomare: the long seafront promenade with its early 20th-century buildings stretching away from the old town.
The sea walls and the old town
The fort makes most sense when you see it as part of a whole. Bari Vecchia is a dense peninsula of lanes, courtyards and churches, still enclosed on the sea side by walls. Walking the Muraglia from the fort towards the Basilica di San Nicola shows how the old town was built to face the sea and protect itself from it, and how the modern city grew up behind it in a regular grid.
Tips for your visit
- Come in the late afternoon or at sunset: the light on the stone and the sea is at its best, and the walls are lively with locals out for a stroll.
- Check the city's event listings if you want to see inside, as the interior usually opens only for exhibitions and events.
- In summer, bring water and a hat: there is little shade on the seafront in the middle of the day.
- Combine it with a loop of Bari Vecchia: along the Muraglia to San Nicola, then through the lanes to the cathedral and the castle.
Nearby
- Basilica di San Nicola: the great Romanesque church that holds the relics of St Nicholas, a few minutes' walk along the sea walls.
- Cathedral of San Sabino: Bari's Romanesque cathedral, deeper inside the old town.
- Castello Normanno-Svevo: the castle on the western edge of Bari Vecchia, with museum spaces inside.
- Teatro Margherita: the theatre built on stilts over the water at the end of the old harbour, now an exhibition venue.
