The Flannan Isles Lighthouse Mystery
Flannan Isles, United KingdomDecember 15, 1900
In December 1900, a relief crew arrived at the Flannan Isles lighthouse off Scotland to find all three lighthouse keepers had vanished. The logbook showed increasingly erratic entries. No bodies were ever found, no explanation was ever confirmed. It remains one of the great maritime mysteries.
