This crannóg (known as Coolanlough Crannóg) has had a rough time of it. It’s believed to date back to the 1600s and was supposedly built and inhabited by the McDonnells who had territory on Fair Head (where the crannóg is located).
A very defensible site, back in the day, it also had a stone wall that surrounded it’s exterior.
In Penal times, it’s isolated location meant it was used for Catholic masses but that came to an abrupt close when the boat going out to it was overloaded with the clergy and worshipers, and tipped over. Apparently, quite a few of them drowned.
Years later, the crannóg actually caught fire and the soil making up much of the wall burned well, which is why it’s so small today.
I was actually visiting this site when I decided to set the next book (The Metal Men) on a crannóg.
