At the lower end of the important and once heavily
industrialised Carnon Valley is the southern terminus of the
Redruth & Chasewater Railway (1824) and the important copper
mining port of
Devoran which dates from the late 1820s and 1830s. It was
built by John Taylor. Though its wooden wharf has largely
disappeared, there are the remains of ore-storage bins, granite
mooring-bollards and various former port buildings, now in private
use.
The remains of this creek-side engine house (1823,
Listed Grade II) mark the unique Carnon Stream Mine that worked
tin gravels in the river bed from shafts sunk within artificial
islands out in the river itself.
