Cezanne's father purchased a large mansion called Jas de Bouffan on the outskirts of Aix-en-Provence in 1859. Cezanne stayed frequently in Aix at the beginning of the 1880s where he painted the surroundings of the estate. This work was painted near the back gate of the estate. The undulations that continue from the back entrance and wall to the distant range of mountains are precisely expressed in a long narrow strip of blue, blue green and ochre that maintains Cezanne's firm sense of spatial order.
