Discover Alfonsino Castle
Discover the history and charm of Alfonsino Castle in Brindisi, an unmissable place for every visitor.
The Alfonsino Castle is a 16th-century fortress on Sant'Andrea Island. It's at the entrance of Brindisi's port. You can only visit with a guide, and it costs 8 euros. Book your visit on PastPuglia.
Tours run daily at 11:30 AM and last about 50 minutes. On Saturdays and Sundays, there's also a sunset tour at 5:30 PM. The light changes the stone to a warm red, and boats start moving around the fort.
The easiest and cheapest way to get there is bus number 5 from Brindisi's train station. Tickets cost 1.10 € per ride (2.20 € round trip) and are sold at authorized sellers like tobacco shops and bars. Onboard purchase is rare. The bus stops near the tourist port, about 400 meters from the castle entrance. If you prefer a sea view without entering, private agencies offer catamaran tours. It's scenic but misses the inside.
Be careful with the motorboat from the waterfront to the Casale. It doesn't reach Alfonsino Castle because Casale is farther and on another part of the port.
There's a plan to extend service to the castle area, so check ahead. Open the map (public transport section) to see updated schedules and connections.
The castle is on Sant'Andrea Island, linked to land by an artificial dam. Its walls drop straight into the sea, built right on the rocks. The fortress looks like it's floating on water. It's made of carparo, the local stone. By day, it seems like a compact military structure. But in the evening, with softer light, it feels more like architecture than defense.
The surprising part, hidden from outside, is the inner dock. It's a water basin enclosed within the castle. Originally, it was the only access point. You could only enter from the sea through an arched entrance for boats. Bastions and walls blocked every other way. You can still sense this logic today. It feels like a small protected port, built to control who came and went from the fort.
Castello Alfonsino isn't a must-see. If you're in Brindisi for a day and want to explore the historic center, the Duomo, the Roman Columns and the Staircase, you can skip it. These sites are all close by, just minutes apart on foot. But if you have more time, it's worth the detour. From the castle, you get a unique view of the port, with its deer-head shape and Roman columns in the background.
If you decide to visit, book the 5:30 PM slot on Saturday or Sunday. On weekends, there's a guided tour in English. During the week, you get an audio guide. Spend fifty minutes inside the castle, then head back to the center. Brindisi at night is magical: local spots, nightlife on the waterfront, people strolling late.
