Located at Malaucène, in the Vaucluse department, the Notre-Dame-du-Groseau chapel is a religious building classified as a Historical Monument. Nice example of Provencal Romanesque art, it is today the only remnant of the Groseau monastery founded at the end of the 7th century by Petronius, then bishop of Vaison-la-Romaine. Destroyed in the eighth century, then rebuilt in the eleventh century, it was the privileged retreat of Pope Clement V.
Destroyed, then rebuilt, the chapel Notre-Dame-du-Groseau now includes two buildings in a single enclosure. The chapel Saint-Jean-Baptiste, to the south, is the oldest, the chapel Notre-Dame being more recent. The latter has a square plan and is surmounted by an octagonal dome adorned with tetramorph. A statue of the Virgin is also installed on an old votive altar dedicated to a former Celtic god.
The Notre-Dame-du-Groseau Chapel was once the subject of many pilgrimages.
