The population in 2011 was 19,880, in an area of 219.26 km². The region of Mangualde has been a crossroads of many peoples: Viriathus's warriors, transhumance shepherds, Romans, Moors and Christian conquerors, including soldiers from Castile or France, or even pilgrims. Mangualde was an important outpost in the textile trade from Covilhã, Seia and Gouveia. Its location, on the frontier with the Serra da Estrela and marginalized by its geography to north, was nonetheless a channel of pre-historic cultures associated with the dolmens that are found through the region. The mount of Nossa Senhora do Castelo, is one such example of the pre-Romanic castros that were used by the early settlers, then reappropriated by the Roman soldiers as forts.
