Dorinish Island, among the most westerly of Clew Bay's islands – of which there's said to be one for every day of the year – was snapped up by the late former Beatle in 1967 as a retreat from his hectic rock'n'roll lifestyle.
But Lennon never actually built a holiday home on the island, and it was sold on to its current owners by Yoko Ono after her husband's death in 1980.
The last time Dorinish was actually inhabited was in the late 1800s, when marine pilots who guided ships into nearby Westport Harbour set up their homes there.
But that might change in the hands of the right owner and the requisite planning permission!
