Okay, this isn’t exactly considered one of the churches in Rome:
Constantine built St. Lawrence Outside of the Walls Basilica, just outside of Rome over the tomb of St. Lawrence, a martyr and one of the first deacons of Rome. Today it remains a shrine to the saint, as well as St. Stephen and St. Justin.
Venice is a city of immense beauty and historical significance, but it is also unique and not like any other city in Italy. Today, it remains an important economic center and is one of the most popular cities for tourism in the world – Sights like St. Marks’s Basilica and the Grand Canal draw millions of visitors to this small group of islands on an annual basis.
