Siena’s Fortezza Medicea (the Medici Fortress sometimes called the Fort of Saint Barbara) is a fort built in the city between 1561 and 1563 on the orders of Duke Cosimo, a few years before he became the first Grand Duke of Tuscany.
The fortress is positioned on the northern edge of the central Siena in the Terzo of Camollia, next to the neighborhood of San Prospero, and since 1923 has overlooked the city's Artemio Franchi/Montepaschi Arena.
