All roads in this ancient settlement - its first charter was granted by king Sancho I in 1199- lead up to the hilltop granite castle. A document dated 1258 describes the construction: the lofty donjon, walls, bulwarks and the noble residence. Breaking this austere design, on the western wall, there is a fine twinned Manueline window finished with the symbols of Manuel, the armillary sphere and the shield of the Cabral family with its two goats. The family's most famous son is undoubtedly Pedro Álvares Cabral. Discovering Brazil in 1500, he had been born in Belmonte in 1467.
