The only watermill on the River Thames still in commercial work under water power, Mapledurham Mill dates from the medieval period and was restored to working order in 1977 after several years of idleness.
Inside, the structure retains its medieval atmosphere. Several of its ancient oak beams have been accurately dated using the technique of dendrochronology.
Bonwick MHC was asked to carry out an assessment of the waterwheel’s condition. This highlighted a need for an overhaul of the fixings on the wheel, as well as for several new paddles, in traditional elm, to replace those which had become weakened through continual wetting and drying. New paddles were fitted to the wheel in 2004 as part of ongoing work to maintain this important mill in working order.
