[WorldCase] The 1900 Disappearance of Three Lighthouse Keepers
This is the mysterious disappearance of three lighthouse keepers on the island of Eilean Mòr, part of the Flannan Isles off the northern coast of Scotland, in 1900. The case is considered one of the most famous maritime mysteries along with the Mary Celeste.
1. Overview of the Incident
To improve maritime safety in the rough waters of the North Sea, a lighthouse was constructed on Eilean Mòr. Although it was originally scheduled to be completed in three years, it was delayed and finally finished in December 1899. Three lighthouse keepers—Thomas Marshall, James Ducat, and Donald MacArthur—were stationed there.
On December 15, 1900, passing ships reported that the light from the lighthouse was no longer visible. Due to storms, the investigation team could not reach the island until December 26. No one was found on the island, and the lighthouse was in proper condition, with its last log entry dated December 15.
2. Theories on the Disappearance
An inspection of the area revealed signs of severe storm damage on the west landing area, with twisted railings and large rocks washed ashore. However, there were no storms reported on that day, and only two of the three waterproof coats were missing. Considering the rule that one keeper must always stay inside the lighthouse, the situation was highly unusual.
This led to various theories such as ghosts, sea monsters, or kidnapping by foreign spies, but no evidence supported them. The most likely explanation is a sudden rogue wave or rip current. The island's geography features cliffs, coves, and sea caves, which can cause violent waves even without a storm. It is assumed the keepers were swept away while trying to secure equipment or warn each other of danger.
3. Aftermath
The mystery has been featured in media such as Doctor Who, the opera The Lighthouse, and the 2018 film The Vanishing (Keepers). The lighthouse continued to be operated until it was automated and became unmanned in 1971.
