Foula, Shetland Islands, Scotland

"Foula, or Fughley as it was once also known, means literally 'Bird Island', with an estimated half million birds of various breeds sharing the rock with the inhabitants. The island’s surface largely consisting of a peat bog on rock."
A lighthouse at the southern tip of the island was built in 1986. Originally powered by acetylene gas, it has been converted to solar and wind power.
