Small weddings in Rome with just the bride and groom, a few friends or a few family members are quite common. If you would like to have your wedding in a church then one of the best for a small group is the Irish College. They have their own church at the college which is modern and small and feels comfortable with just a few people, the grounds are very pretty and great for photos after the ceremony.
The Irish college has another beautiful church a short walk from the college, it is the Baptistery chapel at St.John Lateran, San Giovanni. This is one of the oldest Christian buildings in Rome and full of character. The baptistery is open to the public and tours but the chapel is kept totally private for weddings. They are very strict about this and will close the door during the ceremony.
San Silvestro in Capite works well although it is much larger. St Isidore’s college Rome is also small but can hold up to 100 people, they provide catholic marriages for Irish couples, St Isidore’s is stunning and works really well for small groups. St. Patrick’s in Rome is another church providing Irish wedding.
