By the Restoration, the Spanish commander, xc3x81lvaro de Viveiros, resisted for eleven months (from 27 March 1641 to 4 March 1642) behind the walls of the impregnable fortress, and only a concentrated task force commanded by Francisco Ornelas da Cxc3xa2mara and Joxc3xa3o de Bettencourt were able to defeat the commander.
The fort was taken, and reclaimed for Portugal: a church was constructed within the fortress in honour of Saint John the Baptist (Portuguese: Sxc3xa3o Joxc3xa3o Baptista) after 1642.
The fortress, which includes a primary bulwark and encircled by 4 kilometres (2.5xc2xa0mi) line of walls with four hundred pieces of artillery, used to protected shipping that returned from the East Indies (laden with gold and silver).
At that time, the fortress was renamed to correspond with the name of the church.
