“Reminds me of the movie “The Edge of the World” which was set on Hirta tho actually filmed on another almost identical Scottish Island.
The thing which fascinated me is the remote island had supported human habitation for at least 2000 years then they finally gave up and moved to the mainland in the 1930s or maybe 1920s.
I'll guess they moved because by that time the mainland folk were living much more modern lifestyles.
