The subject of the painting is the Montagne Sainte-Victoire in Provence in southern France. Cézanne spent a lot of time in Aix-en-Provence at the time, and developed a special relationship with the landscape. This painting represented the Mont Sainte-Victoire seen from Montbriand in Aix-en-Provence.
Moreover, Cézanne depicted the railway bridge on the Aix-Marseille line at the Arc River Valley in the center on the right side of this picture.[2]
