St. Paul's Within the Walls, also known as the American Church in Rome, is a church of the Convocation of Episcopal Churches in Europe on Via Nazionale in Castro Pretorio, Rome. It was the first Protestant church to be built in Rome. Designed by English architect George Edmund Street in Gothic Revival style, it was built in polychrome brick and stone, and completed in 1880.
The church contains mosaics which are the largest works of the English Pre-Raphaelite artist Edward Burne-Jones.
