The Lutetian limestones were used to build numerous historical monuments in the north-east part of France. In Rheims, Laon and Soissons areas more than 400 underground quarries have been inventoried, by research regional archives, on old maps several months ground prospecting. Actually, most these are abandoned. Only 3 now open, area. Rheims region, last active quarry, located at Courville village, was closed 2005, because safety conditions. aim study demonstrate importance geomorphological context fracturing network quarry spatial organisation. Underground topography, measurement, aerial mapping analysis features show high connection between natural constraints extraction choices may explain progressive disappearance building stone a studied east area, where usable limestone has weak thickness important mechanical distension stress, galleries direction depends network. contrast, west (Soissons area), shows thick homogeneous facies that allow rational using room pillars mining system.
