Higher BalTrewellard, Cornwall
Higher Bal was a tin mine near Levant.
Originally part of a mine called Spearn Consols, Higher Bal became part of Levant Mine in 1877.
There are two archways in the massive retaining wall; the first gives access to Guide Shaft, now grilled to allow safe viewing; the second leads to steep steps up to the engine house.
This engine was both a pumping and a winding engine.
Take care if you’re exploring here as there are some unguarded drops.
They say it only produced a few tons of tin during its working period, from 1844.
