Very little information can be found on this this quarry. Crisp Delf is shown on the 1848 map and was operated as a flagstone quarry by a William Marsh, the quarry employed approx nineteen men, It is not known when the extraction of flagstone finished.
Throughout the quarry the roof is heavily supported by the use of concrete blocks, the area of unsupported roof is quite staggering, it is thought that the blocks were installed when the quarry was reputedly used as an ammo dump? This may well be true as the floor of this place is not that of your typical quarry.
