The National Museum of Resistance and Freedom, inaugurated on 27 April 2024 to mark the 50th anniversary of Portugal’s Carnation Revolution and the release of political prisoners.

The project, led by architect João Barros Matos, was co-funded by the Portuguese state and the European Union through the Portugal 2020 programme.

From 2019 to 2024, the fortress was carefully conserved, restructured, and adapted to its new role. The project embraces the site’s layered identity, recognising its ‘fortress time’, ‘prison time’ and ‘museum time’ as integral to its historical significance.
