The castle’s keep tower was constructed during the reign of King Dinis in the early 14th century.
The fortification was strategically vital during the Restoration War in the 17th century.
The museum housed inside focuses specifically on regional military history and the town's role in the Napoleonic Wars.
The current tower replaced an older fortification that had fallen into disrepair by the medieval period.
The defensive walls were modified significantly in the 17th century to accommodate artillery, though most were later demolished to allow for urban expansion.
The Castelo de Chaves, or Castle of Chaves, is a medieval fortification in northern Portugal characterized by its solitary 14th-century keep tower. Originally part of a larger defensive line protecting the border with Spain, today only the keep and segments of the surrounding wall remain. The tower structure is built from granite masonry and features a crenellated parapet typical of Gothic military architecture. It currently serves as the Museu Militar de Chaves, housing a collection of artifacts related to the region's long military history. The interior exhibits span multiple floors, detailing the strategic importance of this frontier town. The castle is located within the historic center of Chaves, overlooking the Tâmega River valley. It was classified as a National Monument of Portugal in 1938.
