Built by Frederick II in 1227 with materials from earlier buildings, the Swabian Castle of Brindisi, known also as “land castle” stands in the heart of the city.

The Castle's construction and the many modifications it has subsequently undergone, are linked to some of the most influential figures in Italy's and Puglia's history. It was subsequently restored by the Angevins, expanded by the Aragonese in the 15th century, and fortified by Charles V in the 16th century.

It was used as a prison in the 18th and 19th centuries, before becoming the residence of the Royal Family in the 1940s, after they had fled from Rome.

During World War II, between September 1943 and February 1944, the Castle served as the residence of Italy's King Victor Emmanuel III, his wife Queen Elena, and General Badoglio. Having fled from Rome, they set up base in the Castle, thus making Brindisi Italy's temporary capital.

Nowadays the Castle is used by Naval Command.
