A Castle Steeped in Warfare and Ghostly Tales
Unlike Carreg Cennen Castle, which stands in eerie isolation atop a limestone cliff, As I explored in my previous blog. (here )Kidwelly Castle is a fortress built for war Standing proudly on the banks of the River Gwendraeth. This imposing Norman stronghold has witnessed centuries of battles, sieges, and bloodshed. But beyond its formidable stone walls, whispers of ghostly figures and tragic spirits still linger. Hinting at a past that refuses to be forgotten. As I explored the castle grounds, the weight of history was undeniable. Some claim that Kidwelly Castle ghost stories are just legend, while others insist that something lingers in the ruins—a remnant of its violent past.

The Shadowy Figure of Gwenllian ferch Gruffydd
One of Kidwelly Castle’s most famous ghostly figures is that of Gwenllian ferch Gruffydd, a Welsh warrior princess who fought to defend her homeland. In 1136, Gwenllian led an army against the Norman forces occupying Kidwelly, but the battle ended in tragedy—she was captured and executed near the castle walls.
Many visitors report seeing a shadowy figure of a woman in armor, standing near the battlements or walking along the riverbank, as if still searching for vengeance. Some even claim to hear distant battle cries carried on the wind.
Is this the restless spirit of Gwenllian, forever tied to the battlefield where she made her last stand?

The Weeping Woman of the Chapel
Deep within the castle ruins lies the remains of the chapel, a place where many have reported a ghostly woman in white, kneeling as if in mourning. Some believe she was a noblewoman who lost her family in one of the many sieges that plagued Kidwelly.
Visitors often describe a sudden chill in the air, an overwhelming sense of grief, and even the faint sound of soft sobbing echoing through the chapel walls.
Is this a spirit trapped in eternal sorrow, or just the power of suggestion in a place steeped in tragedy?

The Phantom Soldiers of the Gatehouse
Given Kidwelly’s long history of warfare and rebellion, it’s no surprise that some of its former warriors might still be standing guard. Several accounts tell of ghostly figures patrolling the gatehouse, appearing only for a brief moment before fading into the stone.
Some paranormal investigators claim to have recorded strange voices, whispers of long-forgotten soldiers who once fought to protect this fortress. Could these be the echoes of warriors long past, or merely the mind playing tricks in the dimly lit corridors?

One of the most legendary figures tied to Kidwelly Castle is Gwenllian ferch Gruffydd, a fearless Welsh princess and warrior who led a rebellion against Norman forces. Her bravery in battle has immortalized her in Welsh history, and to this day, she is seen as a symbol of Welsh resistance.
