The chief attraction of Allenheads Heritage Centre is the recently restored Armstrong Hydraulic Engine, pictured above – or, to give it its full title, the ‘W.G.Armstrong twin cylinder, double acting hydraulic engine’. It was made and supplied by the famous industrialist for his friend, the almost as well-known Thomas Sopwith, who at the time was agent of the town’s lead mine.

The water-powered mechanism was one of several that ran machinery in the mine’s yard, primarily the saw-mill and the ore crusher. Installed in the 1840s*, it was fed by Spring House and East End reservoirs high in the hills above the town – and remained in service, remarkably, until 1960. After lying unused and then derelict for a couple of decades, it was rediscovered in 1986 and subsequently restored to full working order.

It is believed to be the last remaining engine of its kind in the world.

* The installation date of the engine does not seem to be precisely known. Some sources give this as early as 1846, but as Armstrong’s mighty Elswick Works in Newcastle were not founded until 1847, this seems unlikely. Sopwith’s diary entries for 1856 indicate that Armstrong’s ‘hydraulic machines’ had by then been up and running for some time.

Catcleugh Reservoir and Byrness Church (NT735034 & NT771023)

Catcleugh Reservoir sits in the upper reaches of Redesdale a few miles short of the Scottish Border. It is now dwarfed by its much larger and newer neighbour, Kielder Reservoir, but at the time of its construction during 1884-1905 it was a truly major concern.

It was built for the Newcastle and Gateshead Water Company in order to feed the growing and ever-thirsty Tyneside conurbation – a series of tunnels, aqueducts and other reservoirs taking the water thus accumulated the 30-odd miles to its destination to the SE.

The River Rede feeds the sizeable body of water, but such is the remoteness of the spot in question that labour and machinery had to be brought in from far and wide to complete the mammoth task. As a consequence of this, two hutted communities grew up in the shadow of the construction site, and were christened ‘Newcastle’ and ‘Gateshead’ for obvious reasons.

A total of 40-odd huts straddled the two semi-permanent townships, housing more than 700 folk – workers, their spouses and their children. It was a tight-knit, rag-tag collection of individuals, who, nevertheless, maintained all the very basic social necessities of a village-like existence. It must have been tough, but there were dances, sports, drinking and gambling to be enjoyed, too … much of it quite illegal!

Today a single workers’ hut remains, which houses an exhibition of the history of the reservoir and its little community of yore. But, most poignantly, in nearby Byrness Church (said to be the smallest in Northumberland) can be found a commemorative plaque and splendid stained glass window – the former listing the names of the 60+ individuals who died during the construction work, and the latter featuring images of the workers themselves. It was all paid for by the community itself, the window being unique in Britain in terms of its subject matter.

An image of the church window can be found here. More info on the extraordinary Catcleugh scheme can also be found here.

Water to Newcastle (NY968763 & thereabouts)

When we think of the water supply provided to the region, the mighty Kielder Water springs instantly to mind. However, a number of other reservoirs form part of the intricate network of watery connections that keep the North-East quenched – with three of the most important crowded into a few square miles of the Northumbrian countryside about eight miles north of Hexham.

Colt Crag, Little Swinburne and Hallington Reservoirs were all built a long time before the 1970s creation that is Kielder Water, being completed, as they were, in 1871 (East Hallington), 1884 (Colt Crag), 1886 (Little Swinburne) and 1889 (West Hallington). Their construction finally brought to an end centuries of struggle to feed an ever-thirsty Tyneside, all but banishing the threat, finally, of typhus – to say nothing of the needs of fire-fighting. Prior to this, glorified ponds on the Town Moor, Arthur’s Hill and at Carr Hill, Gateshead, struggled manfully against the booming populations either side of the Tyne.

Between the ‘heyday’ of the aforementioned ‘ponds’ and the new complex of 1871-89, Whittle Dene Reservoirs (completed 1848), a little to the SE, carried the responsibility of water supply for the area. And, when it was ready, the Hallington/Swinburne/Colt Crag supply was bolted onto the Whittle Dene system before being piped to Newcastle and Gateshead. The network was further extended in 1904 when Catcleugh Reservoir near the Scottish border was brought into use. And then, seventy years later, there was Kielder.

The really quite amazing (and largely hidden) system of tunnels, pipes and aqueducts that connect these large expanses of fresh water both to each other and their points of service was the result of the work of the Newcastle and Gateshead Water Company… and is one of the hidden wonders of the Great North-East.
