Tucked into a bay at the top of the Argyll Peninsula on the central west coast of Scotland, Oban is a ferry port for the islands and a center for Gaelic history and culture. McCaig's Tower, a replica of the Colosseum of Rome, was built in 1900 by a local banker. Argyll, home of the Clan Campbell, was once the ancient Scottish Kingdom of Dalriada. In mist-shrouded Kilmartin Glen, one of the most beautiful in Scotland, are the ruins of Dunadd Castle, where a weathered rock inscribed with a boar head marks where Scottish kings were crowned until the 11th century. Nearby, stone circles attest to a civilization dating back 5,000 years. Loch Fyne is where the present head of the Campbells, the Duke of Argyll, makes his home at Inverary Castle. The 19th century castle was admired by Sir Walter Scott as a fine example of the Scottish baronial style.
