The Floating Lady of Caernarfon Castle
Located in Gwynedd Wales on a peninsula bounded by the River Seiont and the Menai Strait, Caernarfon Castle was built by Edward I of England as part of his iron ring of castles to control Wales.
Caernarfon Castle has a distinct pattern of stone that make up the outer walls, resembling the walls of Constantinople that Edward saw firsthand during the Crusades. Edward used Caernarfon has his seat of power in Northern Wales. The castle was never fully completed as attentions and finances turned to support the struggles in Scotland, but it was attacked a few times by the Welsh and also saw action during the English Civil War when it was besieged three times by Parliamentarian forces trying to uproot Royalists hiding within the castle.
Given its turbulent past, it is no surprise that Caernarfon Castle has a resident ghost...
Though this is not the ghost of a medieval or Roman soldier as one might suspect, but of a woman. The ghost of this female and sometimes glowing phantom has been spotted floating through the air, down the corridors of the castle. It has been reported that electrical equipment left at the castle overnight has been found tampered with upon returning to the castle the next day, often unexplained and then ascribed to the Floating Lady of Caernarfon Castle.
