Castelo e Muralhas de Monsanto

According to legend, the foundation of this castle began with a hillfort that allowed Viriato's companions to withstand a seven-year siege. Later, it also withstood Arab, Castilian, and French attacks. It is located amidst a rocky outcrop, at a strategic lookout point. Dom Afonso Henriques granted it a charter in 1174 and donated it to the Templars, who built the castle. Of the imposing medieval fortress, only the quadrangular Torre de Lucena and Torre do Pião remain.
