Cidadela de Cascais has historically been a fundamental element in the defense of the Lisbon vicinity. Over the last four hundred years, this fortified structure has suffered a number of alterations, and, derived from the end of its use as a military compound, some degree of degradation in its interior spaces.
The renovation project sought to respect the compound's former use as a military structure, adding value to the structure. As most military structures of the type, the Cidadela's spaces are all organized around a central square, surrounded by four buildings.
The architectural intervention consisted, on one hand, on a literal renovation of the existing constructions, adapting them to a hospitality use. On the other hand, the architects built a new, elongated volume inside the historical compound, using contemporary materials and building techniques. The new building, clad in Cor-Ten steel, occupies the space of the former military mess hall, a construction which had no historical value.
