| Description |
Ancienne carrière de tuffeau. Le tuffeau blanc, encore appelé tuffeau de Touraine, de Saumur ou de Bourré, a été abondamment employé, pour les constructions tourangelles et angevines. Dès l'époque gallo-romaine, des carrières de tuffeau on été exploitées en Anjou et en Touraine pour l'édification de bâtiments. L'extraction du tuffeau en galeries souterraines a été la technique d'extraction la plus fréquemment utilisée. Le carrier attaquait le front de taille à l'aide d'un pic. Les dalles qu'il abattait avoisinaient les 3 mètres de haut par 2,5 mètres de large sur 0,4 mètres de profondeur. Ces blocs étaient ensuite débités manuellement sur place en pierres de dimensions diverses. Le tuffeau "prétaillé" était ensuite sorti des galeries.
White limestone, still called tufa Touraine, Saumur or Bourre, has been extensively employed for the Touraine and Anjou constructions. Since Gallo-Roman times, limestone quarries have been exploited in Anjou and Touraine for the erection of buildings. The extraction of limestone underground galleries was the extraction technique used most frequently. The quarryman attacked the coalface using a peak. Slabs that felled were around 3 meters high by 2.5 meters wide and 0.4 meters deep. These blocks were then sawn by hand at stones of various sizes. Blocks of stone, roughly carved, was then removed from the gallery. |
