St Columba's Cave

I quote from internet sources.. (www.megalithic.co.uk)
"St Columba’s Cave can be found, by those with a love of the remote, on the Knapdale Peninsula. St Columba stopped off here to meditate and minister 1400 years ago, after leaving Ulster, while he awaited permission from King Conal to establish his monastery on Iona".
For me, an interesting find. Maybe not so for the Memsahib...

The cave has been used on and off since the middle of the Stone Age and St Columba’s font is believed to have been a Stone Age mortar. Some way in, on a rock shelf to your right, is a stone altar and carved on the wall behind is a rustic, but clearly identifiable, cross".
