Blackhall Mill

Blackhall Mill is first shown on Armstrong's map of County Durham, published by Thomas Jeffreys in 1768. This is a small hamlet of approximately three cottages on the north bank of the River Derwent. The hamlet is not named on Greenwood's map of County Durham, surveyed between 1818 and 1819, but the paper mill (HER 3406) is shown. 'BlackHall Mills' is labelled on the 1840 Hobson map of County Durham which shows a small nucleated settlement along the river bank with a few outlying buildings and the paper mill to the east.

By the time of the Ordnance Survey First Edition of 1862, surveyed in 1856, Blackhall Mill is a small settlement or farmstead comprising three buildings north of the River Derwent. By 1895, Blackhall Mill expanded along the northern bank with the addition of a school and chapel as well as several other buildings. This expansion continued into the 20th century into the 20th century with the development of terraces as shown on the third edition Ordnance Survey.
