Chepstow Castle, situated on a limestone cliff overlooking the River Wye in Monmouthshire, Wales, is one of the oldest surviving post-Roman stone fortifications in Britain. Construction began in 1067 under the Norman lord William FitzOsbern, making it a pivotal stronghold in the Anglo-Norman invasion of Wales. The castle evolved over several centuries, with significant additions and modifications made by William Marshal and his sons in the 13th century.

Throughout its history, Chepstow Castle played crucial roles in various conflicts, including the English Civil War, where it changed hands multiple times. The castle was eventually abandoned as a military stronghold in the 17th century and fell into ruin.

Chepstow Castle has garnered a reputation for paranormal activity. Visitors and staff have reported numerous ghostly encounters over the years. One of the most frequently sighted apparitions is that of Henry Marten, a regicide imprisoned in the castle for 20 years until his death in 1680. His ghost is said to roam the tower where he was held.

Another commonly reported entity is the specter of a woman in a long white dress, often seen walking along the battlements or through the castle grounds. Some believe this to be the ghost of a noblewoman who once resided in the castle.

Unexplained sounds, including footsteps, whispers, and the clanking of armor, have been reported throughout the castle. In the Great Hall, visitors have described feeling sudden drops in temperature and an overwhelming sense of being watched.

The castle’s cellars are said to be particularly active, with reports of shadowy figures and disembodied voices. Some visitors claim to have experienced physical sensations, such as being touched or pushed, in these areas.
