The remains of ruined settlements, chapels, castles, forts and graveyards indicate that long ago, this area was much more populated than it is today. The various reasons for this include the colonisation of the New World, the migration of people to the cities, the invention of the motor car (thus making transport and communication by sea less important). There is also evidence suggesting that the climate was warmer a thousand years ago. It is established that this area supported a significant population for a long while, and there is archaeological evidence of this going right back to pre-Christian times. Have a look at Castle Sween itself, Kilmory Chapel, the Viking Forts above Castle Sween (Dun a Bhuilg & Crannaig), and St Columbas Cave. These are just some of the interesting sites at Ellary and Castle Sween, and the shortest of trips can take you to equally interesting areas – like Kilmartin Glen, for example.
