It was decommissioned in 1825, and Lieutenant Fulgêncio Gomes dos Santos Vale received orders to collect all the arms material onsite, and transfer it the military arsenal in Lisbon. But, the site was garrisoned in 1831, during the context of the Portuguese Civil War (1828-1834). In this period, the site was commanded by Colonel Manuel de Freitas e Paiva. It was visited by King D. Miguel (1828-1834) on 18 February 1832. When Liberals advanced into Lisbon, they defeated Miguelists in the Battle of Cova da Piedade (also known as the Battle of Cacilhas) on 23 June 1833, forcing their retreat to the Castle of Almada. These forces were defeated on the following day.
