The site of a modern turbine house. A power station which housed a water turbine is located at this location. It provided additional power to the power station upstream (PRN 2373.30).
The turbine house was served by a 380 metre race drawing water from the tail race serving the larger power station upstream. The race is now incomplete, having been breached by floods and riverine erosion 160 metres above the turbine house.
The site of a modern water mill. A suspected water mill is shown on the Ordnance Survey First Edition mapping of 1869 at this location; its purpose is not clear.
It was served by a short race running 140 metres upstream. The OS mapping also shows a tail race extending 190 metres downstream, exiting into the harbour below the bridge. It is not clear if this also served the later turbine house, or whether the latter had a shortened tail race rejoining the river close by. The tail race is now largely obscured, but its line can be picked up intermittently.
The site of a modern tail race. The Ordnance Survey First Edition mapping of 1869 shows a mill race extending 190 metres downstream from a suspected water mill (PRN 2374.30), exiting into the harbour below the bridge at the grid reference provided.
It is not clear if this race also served the later turbine house, or whether the latter had a shortened tail race rejoining the river close by. The tail race is now largely obscured, but its line can be picked up intermittently, and its exit is still visible.

The turbine house stands on the site of a suspected water mill which is shown on the Ordnance Survey First Edition mapping of 1867. The mill's purpose is not clear. It was served by a shorter race running 140 metres upstream. The mapping also shows a tail race extending 190 metres downstream, exiting into the harbour below the bridge. It is not clear if this also served the later turbine house, or whether the latter had a shortened tail race rejoining the river close by. The tail race is now largely obscured, but its line can be picked up intermittently.
The site of a modern mill race. A mill race extended 380 metres from this point to a turbine house located further down the valley (PRN 2374.10) which provided additional power to the adjacent power station (PRN 2373.30). The race is now incomplete, having been breached by floods and riverine erosion 160 metres above the turbine house.
Modern waterwheel. Designed and constructed by a local engineer, Robert Casement, in 1854, and named in honour of the then lieutenant governor's wife, Lady Isabella Hope, the Laxey Wheel is the largest working waterwheel of its kind in the world. The wheel is 72' 6" in diameter and 6' wide, (22.1 by 1.8m).
Technically a 'pitch backshot wheel', water is delivered to the top of wheel via a pipe, running up the core of the masonry pillar that supports the viewing platform, from a cistern high on the neighbouring hillside. The wheel turns a crank which provided power via a system of rods to one of the neighbouring shafts, where a series of pumps raised over 40 gallons a minute from the deepest part of the Laxey mine to the main adit level.
The Laxey mine was amongst the richest sources of zinc, lead and silver anywhere in the British Isles in the later 19th century, but one of the key elements in the successful extraction of the ores was the control of ground-water which would otherwise have flooded the 600m deep mine complex.
There were no natural supplies of coal on the Island and so waterwheels, powered by surface-water, were used to drive the necessary pumps.
The Laxey Wheel or Lady Isabella measures 22 metres in diameter and is 1.8 metres wide. It was built in 1854 and is a pitch back-shot wheel powered by water supplied from a cistern on the hillside.
The viaduct carrying the pump-rods is shown at SC 432853 on the 1957 1:10560 scale Ordnance Survey map. The viaduct leads from the wheel and up the valley to the pump head and engine shaft. The wheel was built to work the pumps in the Engine Shaft some 410 metres away. Its power was transmitted by a sectional timber beam running on miniature, railway-type , bogies on tracks carried on an arched stone viaduct. An extensive system of lades brought water to drive the wheel itself and numerous other pieces of water-powered equipment.
The site of a pump head and engine shaft served by the Laxey Wheel, which is located 175 metres to the south. They date to 1854 and were part of the Great Laxey mine complex.

Sir William le Scrope was inaugurated as Lord of Mann at Tynwald — the first recorded formal installation of a lord at the ancient assembly site. He was executed six years later in 1399, his lordship forfeit.
A legal lease document transferring grounds, enclosures, a mill and premises to Robert Calcott, with warranty against disturbance and appointment of attorneys for possession and seizin.

Two related administrative documents from the Atholl Papers concerning the lease of the Governor's house on the Isle of Man. The first (November 1769) is a rent assessment by appointed valuers Thomas Moore and Samuel Wattleworth, setting the annual rent at 24 pounds Manx currency. The second (June 1770) is a letter from the Duke of Atholl granting approval for repairs (£81 4s 6d) and offering a lease during the Governor's tenure. Relevant to governance structures, post-Revestment administrative relations, and the Duke's retained interests in Manx properties.
Two documents relating to the lease and maintenance of Governor John Wood's residence on the Isle of Man. The first (23 Nov 1769) is an arbitrated valuation by Thomas Moore and Samuel Wattleworth of a reasonable yearly rent (£24 manx) for the Governor's lands and recommendation for house repairs. The second (9 June 1770) is a letter from the Duke of Atholl granting consent to repairs (£81 4s 6d) and offering a lease during Wood's governorship with compensation provisions. Provides insight into post-Revestment governance arrangements and the Duke's property interests.
This is an excerpt from a lease or property grant document establishing the terms under which Robert Calcott may occupy and use certain premises including grounds, enclosures, and a mill. The document outlines required duties, suits, services, and customs to be performed, conditions for forfeiture including wilful waste or unauthorized assignment, and the Earl's covenant regarding lawful seizin of the property.
