The Église Saint-Martin-Saint-Augustin is the oldest parish church in Nice still in active use, its current building dating to the 17th century on foundations that are considerably older. The austere stone facade on Place Saint-Augustin in Vieux Nice gives no hint of the ornate baroque interior, which contains a Pietà attributed (with varying degrees of confidence) to Louis Bréa, the master of the Nice School of painting.
The church is rarely crowded and offers a genuinely quiet refuge from the old town bustle. The sacristy holds several important 15th and 16th-century paintings. Services are held daily and the church is open to visitors most mornings.
