old ballad is sung about this ghost: "My Ladye hath a sable coach, with horses two an four. My Ladye hath a gaunt blood-hound, that goeth before. My Ladye’s coach hath nodding plumes, the driver hath no head. My Ladye is an ashen white - as one who is long dead." The lady is reputed to be from the 17th century. She uses a coach made of the bones of her victims and her hound has one eye. Her curse is to collect blades of grass found in the castle ruins, either until the end of time, or until she finds her peace of mind by collecting all blades of grass from the area. No historical event or person has been identified as a basis for the story. Building materials The surrounding areas of the castle consist of varying but typical underground materials. There are metamorphic rocks rocks of granite, other eruptive materials, and rocks from the devonian period. Additionally, limestone, beerstone (a chemical variancy of limestone) and shale or slate can be found. The oldest part of the castle is made from granite and metamorphic rock. The younger parts of the castle were built from the different types of limestone found in the area, along with shale and granite. Granite was used for the fireplaces, while lead and slate were used for roofing works.
