It looks like maybe a WW1 trench. But I'm not sure since I wasn't around back then and also even if I was my eyes are not grainy and my vision not black and white.

The view, made from an upper, rear window of the Niépce family home in Burgundy, in the village of Saint-Loup-de-Varennes near Chalon-sur-Saône. Representationally the subject matter includes [from left to right]: the upper loft (or, so-called "pigeon-house") of the family home; a pear tree with a patch of sky showing through an opening in the branches; the slanting roof of the barn, with the long roof and low chimney of the bake house behind it; and, on the right, another wing of the family house. Details in the original image are very faint, due not to fading?the heliographic process is a relatively permanent one?but rather to Niepce's underexposure of the original plate.
