They are listed on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales. The castle is a Grade II* listed building and its theatre has a separate Grade I listing. History Early history Powell family The main building was built between 1841 and 1843 by Captain Rhys Davies Powell, to designs by Thomas Henry Wyatt. His younger son, his wife and younger daughter all predeceased him. Powell’s death in 1862 was followed by that of his eldest son in 1864 and his surviving daughter Sarah inherited the estate. After the death of her husband in 1875, the estate was sold. Morgan Morgan After the estate entered into the trust of the Chancery, it was bought by Morgan Morgan of Abercrave for £6,000 in 1876. Mr Morgan and his family, plus his son also called Morgan Morgan and his family, lived jointly in the castle for several years. The family cleared a large plantation of 80-year-old fir trees which stood between the castle and the quarries above, which were said to be home to a local population of red squirrels. Adelina Patti Adelina Patti purchased the castle and surrounding park land for £3500 in 1878 to develop it as her own private estate. Having achieved great success as a singer, Patti spent the rest of her life at Craig-y-nos, leaving it only to sing in the premier opera houses of Europe and to tour the United States. After her second marriage, to French tenor Ernesto Nicolini, she embarked on a major building programme at the castle, adding the North and South wings, the clock tower, conservatory, winter garden and theatre. After making her last public appearance in October 1914, when she sang for the Red Cross and filled the Albert Hall, she spent the rest of her life at Craig-y-nos with her third husband. The castle is a Grade II* listed building. Adelina Patti Theatre The Adelina Patti Theatre is a Grade I listed opera house. Built to
