The Castle of Torres Novas is a medieval castle located in the town of Torres Novas, within the Santarém District of central Portugal. The structure dates back to the 12th and 13th centuries and is part of Portugal's historical network of defensive fortifications constructed during the Reconquista period. It occupies a hilltop position, reflecting typical military architecture of the time aimed at providing strategic surveillance over the surrounding area.
The castle features a well-preserved keep tower (torre de menagem), which is square in plan and represents one of the most prominent elements of the edifice. The walls are constructed from stone and include battlements and arrow slits consistent with medieval military design. Historical records indicate that the castle received a foral (charter) during the reign of King Afonso I of Portugal in the 12th century, and it was later reinforced under King Dinis I in the 13th century.
Over time, the castle transitioned from a military stronghold to a civic and administrative center, and today it stands as a national monument. It has undergone restorative work to preserve its structural integrity and historical significance. The site is open to the public and serves as a cultural landmark in the municipality of Torres Novas.
Archaeological and architectural studies support its classification as a significant example of Portuguese Romanesque and Gothic military architecture. The castle is listed and protected by Portugal's Directorate-General for Cultural Heritage (Direção-Geral do Património Cultural).
