Just look what I found in between the houses...
Actually it's called McCaig's Tower, 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).
The structure was commissioned, at a cost of £5,000 sterling, by the wealthy, philanthropic banker, John Stuart McCaig and was erected between 1897 and his death in 1902, McCaig's intention was to provide a lasting monument to his family, and provide work for the local stonemasons during the winter months. His death brought an end to construction with only the outer walls completed.
