Sant'Isidoro a Capo le Case is a Roman Catholic church, monastic complex and college of the Franciscan Order, in the Ludovisi district on the Pincian Hill in Rome. It contains the Cappella Da Sylva, designed by Gian Lorenzo Bernini, who also designed the funerary monument of his son Paolo Valentino Bernini in it. Since the giving of San Patrizio a Villa Ludovisi to the United States of America for use as their national church, Sant'Isidoro has become the National Church of Ireland in Rome.
