Santo Amaro da Barra Grande Fortress achieved its peak of glory in the 18th century on account of the gold found further inland, the progress of São Paulo Captaincy and, finally, the instability of the Platinum Region border. The irregular design of its current structure, spreading along the natural lay of the land, follows the restoration project carried out by Military Engineer João Massé, sent by the Portuguese Crown in 1714. Portuguese Brigadier José da Silva Paes continued Massé's project and transformed the Gun Powder House into a chapel dedicated to Patron Saint Amaro in 1742. He also built a new store-house with thick double walls on top of the rocks to keep the gun powder temperature and humidity in adequate condition. The crossfire fort - Castro or Estacada - situated within the border area, currently where the Fishing Museum of Santos is built, also belongs to Engineer João Massé.
