Castles of Portalegre District

The Portalegre District features a dense concentration of defensive architecture along the Spanish border. This collection includes the high-altitude medieval stronghold of Marvão and the UNESCO-listed star-shaped Fort of Santa Luzia in Elvas. These sites showcase the evolution of military engineering, from the traditional stone keeps of Campo Maior and Ouguela to the complex bastioned systems designed to withstand artillery fire. Each fortification offers insight into the strategic importance of the Alentejo region during the Reconquista and subsequent border conflicts.
