Penela Castle stands atop the rocky outcrop that gave it its name (peñela, "small stone hill"), dominating the town with imposing walls and towers dating from the 15th and 16th centuries. Founded in the 11th century by D. Sesnando Davides, it formed part of the Mondego defensive line, and its walls still reach 19 meters in height today. From the original fortress arose the castle that later served as a keep. On the walls, facing the Serra da Lousã mountain range, stand out arrow slits and loopholes, marks of its long military life, from arrows to firearms. Penela preserves three historical entrances: the Porta da Vila (Town Gate), the evocative Porta da Traição (Gate of Treason), with its double opening and Moorish inspiration, and the Porta do Relógio (Clock Gate), a reminder of the old breach where two towers collapsed in the 1755 earthquake. In short, a castle small in form, but enormous in history.

Built in the 1st century, the Castellum of Alcabideque, classified as a National Monument, is an impressive Roman structure designed to capture and raise water from the local spring to the aqueduct that led to Conímbriga, three kilometers away. The name "Alcabideque" preserves this memory: an Arabicized echo of the Latin, caput aquae, "mother of water," a direct reference to the spring that fed the entire system.
