Wanlockhead Beam Engine
"God’s treasure house"
The villages of Leadhills and Wanlockhead are known as ‘God’s Treasure House in Scotland’ because of the extraordinarily rich ore deposits beneath them, mainly gold and lead.
The Crown of Scotland was fashioned using Leadhills gold.
Scotland's highest village
At 467m above sea level, Wanlockhead is the highest village in Scotland and dates from the 1680s.
The Straitsteps mine, which is underneath the beam engine, opened in 1710. It was in commercial use from 1793 until around 1850. The beam engine was integral to the operation, helping to pump water from the mine.
The village is now home to the Museum of Lead Mining, of which the beam engine is a focal point.
How did it work?
Wanlockhead Beam Engine was a simple but effective machine.
From a hillside water tank, which no longer survives, water was piped into a wooden bucket on the right-hand side of the machine.
From there:
the weight of the full bucket pushed it down, pulling the pump rod up
as the bucket reached the bottom, it triggered a valve and emptied
as the bucket rose back up, the pump rod was pushed back down
at the top, the bucket was filled again, repeating the cycle
When the site was excavated in 1972, foundations of a horse gin were found beside it. A horse walking around a wooden drum on a vertical shaft provided the power to raise and lower equipment.
