McCaigs Tower Oban

McCaig's Tower is a prominent folly on the hillside overlooking Oban in Argyll, Scotland. It is built of Bonawe granite taken from the quarries across Airds Bay, on Loch Etive, from Muckairn, with a circumference of about 200 metres with two-tiers of 94 lancet arches (44 on the bottom and 50 on top)
