Castle stronghold

Passed through Inveraray and stopped to look round Inveraray Castle, ancient stronghold of the Clan Campbell.
It was pretty impressive as Scottish castles go, dating back to the 17th century and apparently haunted by the ghost of a harpist.
Of course, as I'm of Macdonald descent, I shouldn't be going to such places - but I suppose all the Clan rivalry in the past. Isn't it?
