Fortress of Santo Amaro da Barra Grande

The military complex stands at the southeast of Santo Amaro Island, controlling the maritime access channel to Santos port through its strategic position.

Construction began in 1584 under Philip II of Spain's rule following English corsair Edward Fenton's attack on Santos, with Italian architect Giovanni Antonelli's design.

The fortress represents Portuguese colonial military architecture and contains thirty-two artillery pieces installed between 1723 and 1725 for coastal defense purposes.

The fortress opens to visitors who can explore the fortification walls, barracks, and observation points while learning about colonial defense systems.

The structure served as a political prison during the 19th century and exchanged fire with Brazilian cruisers during the 1885 Armada Revolt.
