In 1677, Sir Thomas Myddelton's brother, Richard, bought the property. When he died in 1796 the courts awarded his estates to his three daughters, Maria receiving Ruthin Castle. Maria moved to Ruthin in 1826 having married Fredrick West in 1798. Maria built a home on the site in 1826.

Her son Fredrick Richard West married Therase Whitby, whose guardian was Admiral Cornwallis, and so begain the Cornwallis-West era. They demolished partof the house and built the existing red sandstone property. In 1963 the ancient castle and mansion become transformed into this luxury hotel.

Ghost? There are many different stories surrounding the castle ghost, known locally as the 'Grey Lady' as she is dressed from head to foot in grey. The most popular of these stories is that she was the wife of the second in command at the castle when it was a fortress and was inhabited by the army of Edward I.

The 'Grey Lady' discovered that her powerful husband was having an affair with a local lady so she took the necessary action and murdered her husband's lover with an axe. When her dreadful deed was discovered, the 'Grey Lady' was sentenced to death. As she could not be buried in a church yard (as this was consecrated ground) it was decided that she be buried just outside the castle walls and her grave can be seen to this day. However, she has never settled and can be seen roaming the castle battlements, and, from time to time, she has been seen outside the present castle.
