Acklington Park Dam.

(NU 203029). The magnificent ironworks dam, by Smeaton, situated on the River Coquet at Acklington Park is one of the finest dams in the country (shown as Weir at NU 20300288 on OS 6 inch 1966). Recommended as grade II. The ironworks building, already listed (as Grade II by DOE), was built 1776 but converted to a blanket mill in 1791; working intermittently until the 1930's. (Shown as Mill (Woollen) at NU 20600295 on OS 6inch 1st Ed 1866). (1)(2)

Horseshoe dam also by Smeaton is of special importance as it is largely unaltered. Possibly the finest 18th century dam in the country. (3)
