Coke's Monument, based at Holkham Hall in north Norfolk, is a 37m column built in 1845 to commemorate the achievements of estate owner Thomas Coke, Earl of Leicester. The edifice illustrates new farming methods, such as crop rotation and soil nurturing, to which Coke espoused, heralding a new dawn of agriculture combined with science.
The monument's plinth shows sculptures of an ox, sheep, plough and seed-drill and the top is surmounted by a drum supporting a wheatsheaf. Coke's work to increase farm yields resulted in the rental income of the estate rising between 1776 and 1816 from £2,200 to £20,000.
It can be seen in the grounds of the Holkham Hall estate which is still owned by the Coke family.
