Dunstaffnage Castle, one of the oldest surviving "castles of enceinte". The castle dates back to the century, making it one of Scotland's oldest stone castles, in a local group which includes Castle Sween and Castle Tioram.
Dunstaffnage Castle was built around 1200 by the MacDougall clan (fact). In the Highland Menage series I have it (called "Duncladach") still owned by the MacDougals, whereas in reality the Campbells took it over long before
Dunnottar Castle became the seat of the chief of Clan Keith in 1639 but is now ruined. Dunnottar Castle is a ruined medieval fortress located upon a rocky headland on the north-east coast of Scotland, about 3 kilometres south of Stonehaven.
Dunstaffnage Castle And Chapel, Argyl, is an ancient site and was a stronghold since the century or earlier. It was held by the MacDougalls, but was seized by Robert the Bruce. Then the Campbells of Argyll were made hereditary keepers of the castle.
