King's Mill, Castle Donington

King's Mill is the traditional crossing point of the River Trent between Castle Donington in Leicestershire and Weston-on-Trent in Derbyshire. The Mill was the farthest point that traffic from the Humber could progress. A lock was installed here to make the river navigable but the business eventually collapsed due to competition with the Trent and Mersey Canal. The mill was used for grinding flints for the pottery industry, locally mined plaster, and dyestuffs when it was owned by Samuel Lloyd of the Birmingham banking company.
