'Entre du Desert Grande Chartreuse', c 1865 .

Photograph of a mountain road in the French Alps, taken by Joguet et Fils. The road leads to the Carthusian monastery where Chartreuse Liqueur is produced. Traditionally, Carthusian monasteries have always been known as 'deserts'. This term is meant to indicate the physical solitude of the monastery; ideally, it is situated in a mountain valley, far removed from contact with the exterior world. Muzet Joguet ran a studio based in Lyon, France, during the 1860s. The studio specialised in topographic photographs and documentary studies of civil engineering works.
