The nearest Essex mill to London, Grade II-listed Mountnessing Post Mill is often photographed and sees many visitors.

Dating from 1807, the mill has been fully restored and is now maintained by Essex County Council and Friends of Mountnessing Windmill.

Visit us on our open days. See dates above.


The present mill was built in 1807, probably incorporating earlier timbers. There are records of a windmill on this site as early as 1477.

It has four floors, four spring sails and two pairs of millstones. It is in full working order and occasionally mills flour. The mill can be turned to the wind by pushing its long tail pole - children on school visits enjoy trying this.

Taken into public ownership soon after it stopped operating in 1933, the mill was fully restored and is now maintained by Essex County Council and Friends of Mountnessing Windmill.
