Cava de Viriato
Viseu
The Cava de Viriato is a significant archaeological earthwork fortress located north of Viseu, Portugal. It features an octagonal shape with strong earthen ramparts enclosing an area of eight hectares and a perimeter of about 2000 meters. The site is surrounded by a moat on the eastern, northern, and western sides, parts of which are still visible and accessible today. The walls have a trapezoidal profile, with a base width of approximately 27.5 meters and a crowning platform width of six meters. Traditionally, the fortress was considered a Roman military camp, possibly constructed by Decimus Junius Brutus Galaicus in the 2nd century BC or by military leaders Petreius and Cassius Longinus in the mid-1st century BC. More recent studies suggest that while a Roman camp existed within the area, the primary construction of the fortress may have been of Arab origin. The site’s defensive moat was historically flooded by waters from the nearby Pavia River and Santiago stream, enhancing its protection. Recognized as a national monument since 1910, Cava de Viriato stands as a remarkable example of ancient military architecture and local heritage.
