Overlooking the vast 140-hectare property of Quinta da Vineadouro, the Castelo de Numão is a rugged medieval fortress whose origins date back prior to the founding of Portugal. The history of the castle is intimately connected to the surrounding lands and the timeless atmosphere of the estate. Visitors exploring Vineadouro's wine tourism routes can look up to or hike toward these impressive stone ruins to enjoy sweeping, panoramic views of the terraced Douro valley, the estate's ancient old vines, and the distant Douro River. It serves as a dramatic and historical backdrop that perfectly encapsulates the magic of the Douro Superior region.
