Around midnight on December 15th of 1900, a transatlantic steamer called the Archtor was passing by the Flannan Isles when the captain noticed that the Lighthouse wasn’t lit. After investigating, the lighthouse was discovered to be abandoned and a scene frozen in time remained. This is the story of the Flannan Isles lighthouse mystery.
