This polygon relates to the site of the dam for the Clough (grinding) Wheels / Clough Works (see SMR PRN1738). The present buildings on site are first depicted on the 1938 OS 25 inch to the mile plan. On the 1954 OS this complex included a 'Water Works Depot' and a Gear Cutting Works in addition to the housing to be found on the Charlotte and Edmund Road frontages. This polygon relates to the site of the dam for the Clough (grinding) Wheels (see SMR PRN1738). These were part of the Shrewsbury Estate in the 16th century, grinding being the main activity recorded until the end of the 18th century. By 1810 Crossley (1989) records a 'newly erected scythe manufactory' and it appears that at this time one of the two main 'hulls' was converted to a forging workshop with Miller (1949 p 44) recording that, "A record of 1834 shows that the grinding hull then contained eight edge-tool troughs, and was run by a water-wheel fourteen feet diameter by 7 feet ten inches wide, whilst the forge contained one forge hammer and two tilt hammers driven by a water wheel ten feet diameter eight feet wide. . . There was only sufficient power to run one forge hammer and one tilt hammer at the same time. " (ibid.) Crossley (1989, 110) records that steam power was never introduced at this site having been prevented by a 1845 covenant on the lease, however the 1853 OS shows Clough Works as a manufacturer of steel. Samuel and Robert Linley who were at Clough Works from 1841 to 1881 are listed in the 1879 Whites Directory as manufacturers of Scythes, Sickles, Reaping Hooks etc, as well as other steel goods and advertising their services as Converters and makers of 'Blister, Double Shear and Refined Cast Steel' (advert, 34) indicating the use of both cementation and crucible furnaces. Water power no longer in use on the site after 1891. By 1901 the dam is shown as filled. Invisible legibility of earlier works.
