Conservation of the Great Laxey Wheel

In 2022, Manx National Heritage completed the first phase of an extensive conservation programme, during which the Lady Isabella was carefully studied and conserved.  Procurement for the next phase in this momentous conservation project has now commenced and will see work undertaken on the wheel’s rod duct and T-Rocker.



In the first phase of the project old render and defective timbers suffering decay were replaced, ironmongery repaired and the wheel, housing, railings and viewing platform repainted.  Standing static during her conservation, the world famous wheel began turning again in autumn, concluding the first phase of the most comprehensive conservation project completed on Lady Isabella since her restoration almost 40 years ago.

This unique conservation project offers a rare opportunity to study and work on one of the Isle of Man’s most treasured ancient monuments and the largest working water wheel in the world.  Conservation work of this scale to the Lady Isabella only take place once or twice in a lifetime and the commencement of this project marks a significant moment in, not only the history of the Laxey Wheel but also in our Island’s history.

Designed by the Victorian engineer, Robert Casement, the wheel was completed in 1854 to pump water from the depths of the Laxey mines using water from Glen Mooar to power the wheel. The impressive 22.1 (72.6 feet) diameter structure found immediate popularity and has remained one of the Island’s most iconic and dramatic attractions for over 150 years.



August 2023
Timbers have arrived for phase 2 conservation of the Great Laxey Wheel, where works will commence later this year to conserve and repair the wheel’s magnificent rod duct and T Rocker. 
The timber is all French grown & milled PEFC Certified & QPA Graded Fresh Sawn (Green) Oak. The longest timber is the new Upper Connecting Rod which will connect the top of the flat rod to the top of the T Rocker – it is 11m in length.
The rest of the smaller sections are the main connecting rods. The heaviest timber there is the new T Rocker Main (Bridging) Beam – it is 450 x 450mm square, 10m long and weighs roughly 2.5 metric tonne.
6 more timbers are due to arrive in a few weeks, these are the 6 bearing timbers for the T Rocker, which are 470 x 470mm square & 5m long – FSC Certified Greenheart. They will be over 1 metric tonne each.
Greenheart is a South American hardwood, one of the strongest and most durable timbers available (approximately twice the rating of European Oak), chosen for this application where it will be permanently exposed under significant load in very difficult conditions for any timber – hopefully they won’t need replacing for another 160 years.

7 – 9 Sept 2022 Access to viewing platform suspended for final repairs

Access to the viewing platform will be restricted from 7 – 9 September, when linkage timbers including the Southern Sweep-Arm and L-Rocker are scheduled to be craned into position. There will be no access to the top of the wheel during the installation works.

3 Sept 2022 Conservation work at Laxey Wheel is making good progress

From Saturday 3 September you can climb to the top of The Lady Isabella and take in the magnificent views.  Please note access to the viewing platform may be temporarily suspended to allow for final repairs to take place.

July 2022 A Milestone in the Lady Isabella’s History

Manx National Heritage will reach a milestone in the Laxey Wheel’s history during September when works will conclude in the area around the wheel casing. Scaffolding will be removed during August, with the wheel gradually revealed in all her glory.

Completion of this phase of the project marks a huge moment in the Laxey Wheel’s history and is an achievement for the Isle of Man to be incredibly proud of.  The wheel is unique, iconic and a cornerstone of our visitor experience.  It will be incredibly rewarding to see both local residents and visitors climbing the wheel’s staircase and seeing her turning once again.
