The Church of St. Paul's Within the Walls, also commonly called the American Church in Rome, is an Episcopal Church located on the Via Nazionale, close to the church of Santa Caterina a Magnanapoli.
It was designed by the English architect George Edmund Street, who also designed the Royal Courts of Justice in London, and supervised the restoration of Christ Church Cathedral, Dublin. It has mosaics by the Pre-Raphaelite, Edward Burne-Jones.
The Church was dedicated in 1876, the centennial of the United States, and completed in 1880. It was the first Protestant church built in Rome.
