The Swabian Castle of Brindisi, also called Castello di Terra or Castello Svevo-Aragonese , is located near the historic center of Brindisi, a part of it overlooks the inner part of the city port, also defending this important area of the city.

The Roman Columns of Brindisi are a monument located at the port of the city. Originally they were twin columns, unique in the architectural landscape of antiquity. As such they were depicted as early as the 14th century as the emblem of the city. Following the collapse of one of the two columns in 1528, the monument remained mutable.

Castello Alfonsino (also called Castel Rosso, after the color of the carparo ashlars used for its construction, or Castello di Mare) is a complex fortified work built on the island of Sant'Andrea, at the mouth of the outer port of the Italian city of Brindisi. The castle is adjacent to the Forte a mare (or Fort of Brindisi), whose construction work, begun in 1558, reigned Philip II of Habsburg, son of Charles V, lasted 46 years
