Monolith millstones were the principle product of La
Ferté-sous-Jouarre, France until the early 1800’s.
there was a pronounced change in production to
constructed from a number of stone blocks (French
burr stones) rather than them being of one piece.
researching material on millstones for my soon to be
released book “Watermills & Stoneground Flour
Milling”, I came across a booklet by Owen Ward,2
in which it stated that La Ferté monoliths are rare
outside of France. However, there was mention of one
being on show in Heckington Windmill, Lincolnshire.
I emailed Heckington Windmill Trust to inquire if
the stone was still on view. My intention being to
visit the mill at some time in the future to view
response, Jim Bailey kindly confirmed that it was
still there and very helpfully sent me some
pictures. Jim has agreed to share these with ‘HMG
Newsletter’ readers. The stone is exactly 4ft
(1220mm) in diameter and averages 10.5in (267mm) in
thickness +/- 0.25in (6.35mm). It is banded and has
a rhynd in the eye.
suggested that the Heckington example probably came
from the nearby long-converted watermill of
readers known of another whole or part monolithic
example in the UK? Please do email me at

Millstones from La Ferté-sous-Jouarre, France.
