A very fine pair of wrought iron gates and elaborate overthrow by William Bakewell of about 1722, at the Derby Industrial Museum, on the site of the Old Silk Mill. The gates were formerly erected on the bridge (see plans and photo) crossing the River Derwent to the island where the mill was situated. They are not now in their original position. Grade 1. (1-4) The Old Mill, Full Street. All that remains of Thomas and John Lombe's pioneer factory of 1717-21 is the stone foundation arches of the main mill and the repositioned wrought iron entrance gates by Robert Bakewell of 1725. The present mill dates largely from 1910 when, after a destructive fire, it was rebuilt on its original foundations. (5)
