This is an unusually old example of an engine house and originally housed a 60"
pumping engine. The engine was rebuilt in situ by Harvey in 1857 and worked until
the late 1890s. It was a 'high duty' engine, i.e. an engine that exceeded the
average efficiency attained by pumping engines in Cornwall as recorded in Lean's
monthly statistics.
