Scottish anchorages

Mingary Bay is a surprisingly nice anchorage when the wind is not in the south, well placed for walking up to Mingary Castle rooted to its rock in an amazing position commanding the north entrance to the Sound of Mull and Loch Sunart. It was started in the 13th century and then altered in the 16th, 17th and again in the 18th centuries before falling into disuse in the mid 19th century - not so long ago. Although it was besieged a few times, there is a lot of castle left but at the moment it is not possible to get into it. Whoever owns it - the Ardnamurchan estate I believe - needs to get it made safe before it falls into an even worse state. It would surely be a good place to explore if it was restored. Indeed, in this area it is the only uninhabited castle in reasonable condition that one can't look round. Surprisingly, in front of the entrance across the rock-cut ditch lying in the grass is a very large old cannon - where did that come from? The castle or one of those Spanish Armada ships that was meant to have fetched up around here?
