Blair Atholl's most famous feature is Blair Castle (NN 865 662), one of Scotland's premier stately homes, and the last castle in the British Isles to be besieged, in 1746 during the last Jacobite rising. The Castle was the traditional home of the Earls (later Marquesses, now Dukes) of Atholl. The Duke of Atholl is the only person in the United Kingdom allowed to raise a private army. This army, known as the Atholl Highlanders, conducts largely social and ceremonial activities, and primarily consists of workers on the extensive Atholl Estates.
