Bonawe blast furnace, on the southern shore of Loch Etive, was established between 1752/53, and intermittent iron production continued until 1876.  It has been described as "The Longest-lived Blast Furnace in the Scottish Highlands".  The area was abundant in good quality wood for the manufacture of charcoal.  A visitor centre adjoins the site and is open to the public most of the year.
