The church of San Filippo Neri is a small but finely detailed Baroque church on the corso just north of the main square, attached to the Oratorian congregation founded by Saint Philip Neri in sixteenth-century Rome. The current building dates from the eighteenth century, with a curved facade in mellow brick and stone and an interior that is more elaborate than the exterior suggests: stucco angels, painted vaults, and an altarpiece of Saint Philip flanked by spiral columns.
It is normally open in the mornings and worth slipping into if you are passing along the corso. The church is rarely visited and offers a quiet contrast to the busier Piazza Leopardi a short walk south.
