Cyfarthfa Castle Museum and Art Gallery

A lady with a white cap was seen here, but only visible to a child, and the school area has poltergeist-like activity including chairs moving and heaters turning on.

Update 17/12/21: The castle responded to my Facebook query asking about recent phenomena: "Sorry but we haven't had any ghostly or odd or inexplicable phenonema recently that any of the staff are aware of."
