John Lennon had quite a cheek. In the most famous song he recorded after his time with the Beatles, he sang the line 'Imagine no possessions. I wonder if you can?' If Lennon were true to his word, then for him that process would have involved imagining that he didn't own a beautiful green island in Ireland's County Mayo. Dorinish Island is a windswept land of hills and grass, which is home to some sheep and not a lot else within its 19 acres.
Lennon and his wife Yoko Ono planned to build a cottage there and live there in isolation for part of the year, but sadly never got around to it after Lennon's 1980 murder. After he died, Ono sold the island and gave all of the proceeds to a local Irish orphanage. It's believed that the island is still unoccupied.
