During the siege of Porto (1832-1833), Miguelist forces occupied the fort until Lordelo, even as they were confronted by batteries and the Liberal navy. By the end of the civil war the fort was destroyed. In August 1860, a plan of the fort included drawbridge, residence of the Governor, chapel in ruins, housing for military officers also in ruins, a ramp to the esplanade, moat, areas inundated by the sea, four quarters for soldiers, kitchen, powder magazine and a vaulted house for quarters. It was assigned for the Veterans Company (1839), during the revolt of Maria da Fonte (1846), and occupied by troops from the Junta of Porto, and was bombarded by the frigate "Íris", supporting the government of Maria II.
