This Gothic style chapel is located in the old cemetery of Sainte-Croix. It dates from the 16th century. It is closed by the porch of the old Saint-Donat church, of which it was the south side chapel. It contains the tombstone of Camille de Crues, on which is inscribed the genealogy of the Crues family from 1260 to 1727, and which was classified on the inventory of historical monuments on October 5, 1920. In a state of worrying decay at the end of the 20th century, it was taken out of the air and out of the water by the municipality in 1990, partly thanks to donations from the inhabitants. However, the interior furniture remains heavily degraded and may never be restored, due to costs inaccessible to the municipal budget.
