Site overview
Denver Windmill was built in 1835 for John Porter, replacing an earlier post mill shown on the 1824 Ordnance Survey map. The six-storey tower stands 59 feet to the curb and carries an ogee cap with gallery and six-bladed fantail. Four double patent sails drove three pairs of overdriven stones, with auxiliary steam power later replaced by diesel.
The mill continued in commercial use until 1969, after wind power had given way to diesel in 1941. Restoration followed in stages: the fantail was restored in 1982, further restoration continued from 1984 to 1998, and the restored mill opened to the public in March 2000. Denver Windmill is Grade II* listed and has again milled wheat using wind power.

History
Denver Windmill stands at Sluice Road, Denver, near Downham Market. It was built in 1835 for John Porter, replacing an earlier post mill that was marked on the 1824 Ordnance Survey map. The tower carries a datestone marked JMP 1835.
The large six-storey mill is 59 feet high to the curb. It worked with four double-shuttered patent sails and three pairs of overdriven stones, with the stones on the third floor and a stage giving access to the striking and brake chains. The horizontally boarded ogee cap had a gallery, ball finial and six-bladed fantail.
Steam power was later added and eventually replaced by diesel. John Porter was followed by the Gleaves family and then by Thomas Edward Harris and Thomas Edwin Harris. Wind power ended in 1941, and the mill continued under diesel power until closure in 1969.
The building was later restored. The fantail was restored in 1982, and further restoration took place between 1984 and 1998. The restored mill opened to the public in March 2000.
Later operation returned the mill to traditional flour production, with Denver Windmill recognised as a Grade II* listed working tower mill with associated ancillary buildings.
