Trahamunda was a medieval nun from Galicia, Spain, who is honored as a saint in the Catholic tradition. During the High Middle Ages, she lived as a novice at the San Martín convent located on Tambo island. Following her capture by Moorish forces, she was taken to Córdoba, where she resisted being forced into a harem. This refusal led to her imprisonment for eleven years before she eventually returned to her homeland near the Monastery of San Juan de Poio.
