Built in 1795, Seguin Island Lighthouse is one of Maine’s oldest beacons and carries a chilling legend. According to local lore, a lighthouse keeper gifted his lonely wife a piano, but when she endlessly repeated the same tune, he murdered her before taking his own life. Since then, visitors and staff have reported phantom piano music echoing across the island, along with cold spots and shadowy figures in the tower. The tale has cemented Seguin’s reputation as Maine’s most haunted lighthouse.
