Oratory of Gesù Pellegrino, Renaissance oratory in Historic Centre of Florence, Italy.

The Oratory of Gesù Pellegrino is a Renaissance building at the corner of Via San Gallo and Via degli Arazzieri, where a simple exterior conceals a decorated interior. The space preserves paintings and altarpieces skillfully integrated into its walls.

Formerly the church of San Salvatore, the building passed to a confraternity of that name until 1313, when Bishop Antonio d'Orso established a hospice for pilgrim priests. It was later dedicated to St James, and under Archbishop Antoninus the confraternity added a hospice for elderly priests. Between 1585 and 1588 Alessandro di Ottaviano de' Medici, later Pope Leo XI, commissioned a restructuring directed by Giovanni Antonio Dosio.

The interior walls display frescos and altarpieces showing scenes from Christ's life, which shape the space with religious imagery that visitors notice right away upon entering.

The location sits at Via San Gallo 31 in the historic center and is easy to reach on foot while exploring the area. Most visitors need about an hour to view the interior fully.

Near the entrance, in the nave, stands the tomb of Arlotto Mainardi (1396–1484), a parish priest remembered in Florentine tradition as a wit and storyteller whose sayings were collected under the name Piovano Arlotto. The monument marks a burial inside the prayer hall rather than in a church nave.
