The stone has been
quarried north of Totternhoe village in the county of Bedfordshire. It was quarried at
Totternhoe Knolls, and to the east of the Knolls there were underground
mines for the stone. The area from where the
medieval tunnels were dug is now designated a
Site of Special Scientific Interest (SSSI) called
Totternhoe Chalk Quarry, as an example of
chalk grassland. It is managed as a
nature reserve by the
Wildlife Trust for Bedfordshire, Cambridgeshire and Northamptonshire. In recent times the stone has been quarried in an area between the Knolls and the mines. This has been designated an SSSI called
Totternhoe Stone Pit, as a
Geological Conservation Review site. The Stone is quarried by a family-run business, H.G Clarke and Son. This was started in 1920 by Herbert G.Clarke. It was then passed to his son Stanley W.Clarke and is now being run by his son Angus J.Clarke. H.G Clarke and Son are the main suppliers of this rare English stone. ==References==
