Salúquia, daughter of the Muslim governor Abu Hassan, was the bride of the young castle commander at a time when the entire territory was still under Moorish rule and the Christian kings from the north, especially the first Portuguese king, D. Afonso Henriques, were striving to reconquer the Iberian Peninsula for Christianity.
Leaning against the highest parapet of one of the castle towers, Salúquia awaited the return of her fiancé, who had set out to fight the Portuguese. However, the Portuguese had already occupied the entire area and surrounded the young Moor, who was killed along with his fighters. The Portuguese then dressed in Moorish clothing and, with this disguise, managed to have the castle gates opened for them.
The beautiful Salúquia understood the ruse and, preferring death to a fate as a Christian slave or prisoner, threw herself from the tower. This legend also explains the origin of the name Moura.
