Alfonsino Castle, known also as Red Castle because of the vermilion colour of its stone, sits on Sant'Andrea Island at the entrance to Brindisi’s harbour, in front of the Pigionati Channel.
Construction work began in 1481 under Alfonso II of Naples, who built a tower to guard the port and to serve as a defensive outpost for the city. A few years later, Alfonso of Aragon transformed the original defensive structure into a proper castle.
The Castle was built on a strip of land surrounded by the sea, where there had previously been a Benedictine abbey dedicated to Sant'Andrea (it was destroyed in the 15th century). Next to it is the Forte a Mare (Sea Fortress), which was built in the 16th century to serve as a barracks for the troops.
Nowadays, the Castle can be visited with authorization from the Navy.
