Rocca di Ostia, Medieval fortress in Ostia Antica, Italy
The triangular fortress features three towers, two circular and one polygonal, connected by defensive walkways and surrounded by thick brick walls.
Construction began in 1483 under Pope Sixtus IV with architect Baccio Pontelli to protect Rome's coastal area from Mediterranean pirate invasions.
The fortress contains a monumental staircase decorated with frescoes by Baldassarre Peruzzi, commissioned by Cardinal Raffaele Riario in the 15th century.
The fortress opens every Saturday and Sunday from 9:00 to 17:00, with guided tours available through the Ostia Antica Archaeological Park.
The structure incorporated Martin V's tower and included papal apartments on its western side, marking a transition in fortification architecture.
