The Chiesa di Santa Fosca was founded in the 11th century to house the body of St Fosca. How this Roman girl raised in Libya wound up a saint is a tragic tale: when Fosca announced her conversion to Christianity at 15, her enraged father turned the teenager over to local authorities, but an angel frightened the soldiers away. Fosca calmly turned herself in, and was tortured and bled to death with a sword. After Libya was conquered by the Muslim Ummayads in 655, a Venetian sailor named Vitale brought her remains to Torcello.
