Origin and history

Poussendre polishers were discovered in 1912 on the banks of Laizon, in Bons-Tassilly, Calvados department. These sandstone blocks, marked by deep furrows, were used to polish the axes and flint tools during the Neolithic period. Their presence illustrates the agricultural and artisanal activities of the local people, who cleared the forests to create fields and manufactured essential tools for their subsistence.

A first polisher, located on the right bank of the Laizon, was inscribed as historical monuments on 24 August 1976, as was a second polisher discovered on the left bank. These vestiges, typical of the megalithic sites in the region, reveal the importance of watercourses as places of work and exchange. Several other polishers have been identified in the valley, confirming the intense activity of size and polishing in this area.

The discovery of a nearby polisher in Ouilly-le-Tesson in 1983 reinforces the hypothesis of a network of polishing workshops along the Laizon. These sites, often associated with rock shelters and menhirs such as those of the Longrais, are evidence of continued human occupation since the Paleolithic period. Poussendre polishers, by their state of conservation and registration, are a remarkable example of Norman megalithic heritage.
