Description: Gregory's Quarry near Ancaster has a long history of stone-working dating back to Roman times. Ancaster Stone is the principal stone used in all of the local churches and houses. The stone was also exported further afield to Nottingham (Wollaton Hall, the Adam's Building in the Lace Market, Nottingham) Boston church (St. Botolph's - the famous Boston Stump). The quarry is one of several active quarries in the area still producing high quality Ancaster Stone for building. General view of the active north-west corner of Gregory's Quarry working the Ancaster Stone. Upper Lincolnshire Limestone is being quarried by traditional percussion drilling, plug and feathers wedges and leverage to produce high quality monumental and building stone. Explosives are not used here.The overburden of Rutland Formation clays and fine sands is being stripped off for use elsewhere. Ancaster Stone is one of the principal building stones of the East Midlands. This oolitic and shelly limestone is produced in several varieties - Hard White, Weatherbed and Freestone. The Lincolnshire Limestone Formation is the source of several famous building stones - Ancaster, Barnack, Ketton, Clipsham and Weldon.
