a distant cousin of the Earls of Fife. Vaynol passed in turn to their two eldest sons (the first of whom, George William (1848-1904 ), left no son; his wife and daughter had Snowdon Mountain Railway locomotives named after them ) and they took the surname Assheton-Smith instead of Duff. The younger son, Sir Charles Garden Assheton-Smith, was created a baronet in 1911. He sold 30 farms from the estate in 1914. His son and grandson the 2nd and 3rd baronets, reverted to the name of Duff. Sir Michael Duff, 3rd Baronet had an adopted son, Charles David. At the beginning of the 20th century, the estate amounted to of land and had 1,600 tenants. The Prince and Princess of Wales (later King George V and Queen Mary) stayed there as guests of the Assheton Smiths during a visit to North Wales in May 1902. To celebrate the 1935 Silver Jubilee of King George V and Queen Mary and to improve Caernarfon, the town walls and some adjoining property, which belonged to the estate, was handed over to the Ministry of Works. The estate's remaining property in Caernarfon was offered for sale in 103 lots in 1957. In 1967 21,000 acres, including the north face of Snowdon, was sold to two property companies, jointly, for a reputed £1½ million. Vaynol, its home farm and some adjacent property were retained by the estate trustees and Sir Michael Duff. The Dinorwic slate quarries at Llanberis, which were owned by a family company, were not sold. Later in the year, the property companies sold 13,000 acres of Snowdon land to the Welsh Office for £140,000. Further properties were sold to tenants and 138 lots were offered for sale by auction in 1968. Sir Michael Duff's obituary claimed that the 1967 sale was forced on him by high taxation. Attractions In the second half of the 19th century the park had a zoo, but it was dismantled by 1900. The park has been the setting for Bryn Terfel's Faenol Festival since 2000, and in 2005 it hosted the National Eisteddfod. On 25 August 2006, Irish vocal pop band Westlife held a concert for their Face to Face Tour supporting their album Face to Face. BBC Radio 1's Big Weekend was held at the park in May 2010.
