Hockley Mill was built in 1803 in an annex to a large barn.
It has an unusual horizontal timber main shaft driven by an iron Poncelet waterwheel designed primarily to run machinery in the adjoining barn via a system of belts. It also drove two pairs of millstones.
The barn has now been converted into living accommodation, but the rest of the mill survives more or less intact.
The mill wheel still turns, and can apparently be used to grind corn. These days though, due to fragile state of the gearing, it is normally runs free and is very rarely connected to the rest of the machinery.
Currently the mill is only opened on two Sundays a year: One in May during the National Mills Weekend, and the other in September during the National Heritage Weekend. Please check the respective web sites for details.
