This large rock nestled between Dunollie Castle and the centre of Oban, is known as the Dogstone or Fingal's Dogstone. Many believed that this is where the giant, Fingal, left his dog Bran when he went off hunting across the Hebridean islands. Some have said that you can see the marks from the dog's chain where it circled and circled the stone, trying to break free.
