Built in the 1870s in a Romanesque-Byzantine style, out of pale stone quarried at La Turbie just over the border. It replaced a thirteenth-century church on the same spot.
The princes of Monaco are buried here in the ambulatory behind the altar. Princess Grace — Grace Kelly, who died in 1982 — is among them, and hers is the grave people come for; it is marked simply, in Latin, with flowers most days.
The altarpiece by Louis Bréa, painted around 1500, survived from the earlier church and is the best thing in the building.
Free, two minutes from the palace, and rarely crowded. It is the easiest good half-hour on the rock.
