Reasons for Designation

Approximately 10,000 lead industry sites are estimated to survive in England, spanning nearly three millennia of mining history from the later Bronze Age (c.1000 BC) until the present day, though before the Roman period it is likely to have been on a small scale. Two hundred and fifty one lead industry sites, representing approximately 2.5% of the estimated national archaeological resource for the industry, have been identified as being of national importance. This selection of nationally important monuments, compiled and assessed through a comprehensive survey of the lead industry, is designed to represent the industry's chronological depth, technological breadth and regional diversity. Nucleated lead mines are a prominent type of field monument produced by lead mining. They consist of a range of features grouped around the adits and/or shafts of a mine. The simplest examples contain merely a shaft or adit with associated spoil tip, but more complex and (in general) later examples may include remains of engine houses for pumping and/or winding from shafts, housing, lodging shops and offices, powder houses for storing gunpowder, power transmission features such as wheel pits, dams and leats. The majority of nucleated lead mines also included ore works, where the mixture of ore and waste rock extracted from the ground was separated ('dressed') to form a smeltable concentrate. The range of processes used can be summarised as: picking out of clean lumps of ore and waste; breaking down of lumps to smaller sizes (either by manual hammering or mechanical crushing); sorting of broken material by size; separation of gravel-sized material by shaking on a sieve in a tub of water ('jigging'); and separation of finer material by washing away the lighter waste in a current of water ('buddling'). The field remains of ore works vary widely and include the remains of crushing devices, separating structures and tanks, tips of distinctive waste from the various processes, together with associated water supply and power installations, such as wheel pits and, more rarely, steam engine houses. The majority of nucleated lead mines with ore works are of 18th to 20th century date, earlier mining being normally by rake or hush and including scattered ore dressing features (a 'hush' is a gully or ravine partly excavated by use of a controlled torrent of water to reveal or exploit a vein of mineral ore). Nucleated lead mines often illustrate the great advances in industrial technology associated with the period known as the Industrial Revolution and, sometimes, also inform an understanding of the great changes in social conditions which accompanied it. Because of the greatly increased scale of working associated with nucleated mining such features can be a major component of many upland landscapes. It is estimated that several thousand sites exist, the majority being small mines of limited importance, although the important early remains of many larger mines have often been greatly modified or destroyed by continued working or by modern reworking. A sample of the better preserved sites, illustrating the regional, chronological and technological range of the class, is considered to merit protection.

Park Level mine adit is a good example of the mining technology of the mid- 19th century. The area of shallow shaft based workings on the east bank of the Burn form an important contrast to the later deep adit technology of the Park Level mine adit. The associated ore works with mechanised crushing mill is typical of the majority of nucleated mines of this period. The site is open to the public and has become an important centre for the interpretation of the lead industry of the North Pennines as well as a valuable educational amenity. Part excavation has provided evidence of the operation of the mine and further undisturbed structures and stratigraphic deposits will survive, particularly in the area between the jigger house and the dressing floors, which will contribute further to our understanding of the dressing process. The restored stone lined launder and reservoir to the south west are important to the overall context of the site. They supply the water to power the Wheel and are valuable evidence of the once extensive intergrated water management system which formerly fed the mill.

History

Details

The monument, which lies within a single area, is situated on the Killhope Burn, in the upper reaches of Weardale, County Durham, and includes the buildings, earthworks and other remains of the Park Level lead mine and ore works. All original buildings within the monument are Listed and are also included within the scheduling. The mine lies within a former medieval hunting forest once the possession of the Bishopric of Durham, responsibility for which eventually fell to the Church Commissioners. From 1696 until 1882 the mineral rights were leased to the Blackett-Beaumont family followed in turn by the Weardale Lead Company. The site includes the remains of the Park Level mine with restored mineshop (Listed Grade II), saddle house and mine adit situated on the right bank of the Burn in the south western part of the site. The adit was begun in 1853 as a cross-cutting horse level and driven west to intercept lead veins previously worked by hushing and shallow shaft based workings. The remains of earlier shallow shaft-based workings on the left bank of the Burn are included within the scheduling. The core area of the site, situated on the right bank of the Burn, contains the restored and excavated ore works. The dressing floors and bouseteams (storage bays for unprocessed ore) were built in 1862 with reconstruction in 1874-76 and are Listed Grade II. The dressing floors are an excellent example of manual dressing technology. They include reconstructed timber and stone structures such as hotching tubs, dolly tubs, settling tanks and Brunton buddles. These reconstructions are not included in the scheduling. Excavation and survey carried out in the 1980s has provided evidence of the layout of the site including original settings and foundations. The restored crushing mill, built in 1874-76 and a Listed Building Grade II*, is an excellent example of the more advanced water powered mechanised separation plants of the later 19th century and is included within the schedule. The crushing mill was built to replace the now destroyed Burn Bottom mill, situated 300m upstream, which was unable to cope with the volume of ore produced from Park Level adit. The mill includes the Killhope Wheel, jigger and buddle houses, and the timber framework of the crushing plant. The Wheel (a Listed Building Grade II*) is now the largest surviving waterwheel in the north of England with a diameter of 10.3m. To the south west lie the original reservoir and stone lined launder which supplied water for the wheel. The mill was standing complete in 1919 but shortly afterwards the plant was removed by the Weardale Lead Company for service at other mines still in production. All drystone boundary walls, fenceposts, the revetted retaining wall in the northern part of the site, road surfaces, a reconstructed stone and timber bridge, and the modern reconstructions are excluded from the scheduling, but the ground beneath all these features is included.
