Fortezza Medicea di San Martino, Italian fortress in San Piero a Sieve, Italy.
The fortress extends over 65,000 square meters with 1.5 kilometers of perimeter walls and 17,000 square meters of masonry surface on a hill.
Construction started on June 30, 1569, under Cosimo I de Medici, with architect Baldassarre Lanci designing the structure until completion in 1608.
The fortress represents Renaissance military architecture with nine bastions, two gates named Florentine and Bolognese, and an internal five-sided keep.
Visitors can access the fortress through a path surrounding the walls, with guided tours available to explore the main tower since 2011.
The structure contained facilities for 2,000 soldiers, including windmills, workshops for firearm repairs, water cisterns, and a dedicated chapel.
