The dome of the church of Ss Ambrogio e Carlo, better known as San Carlo al Corso, is one of the most striking features of the Roman skyline.
This grand 17th century Baroque church, which is dedicated to two great bishops of Milan, St Ambrose (c. 340-397) and St Charles Borromeo (1538-84), was begun in 1612 by Onorio Longhi (1568-1619) and completed in 1669, many years after his death. The dome is based on a design by Pietro da Cortona (1596-1669).
San Carlo al Corso, which has a cruciform ground plan, boasts the only ambulatory in Rome. The ambulatory is home to a shrine that houses the relic of the heart of St Charles Borromeo.
