Gwrych Castle was built between 1812 and 1822 for Lloyd Hesketh Bamford-Hesketh. Various architects and designers were involved. The Craches had a hand in furnishing the interiors. Between 1909 and 1914, Arts and Crafts architect, Detmar Blow, in conjunction with Charles Ernest Elcock, added the famous yet theatrical Italian marble staircase and renovated the state apartments.
During WWII, Gwrych was requisitioned by the Government and housed two hundred Jewish refugees. Leslie Salts then bought the building in 1948 and successfully opened Gwrych to the public for twenty years. The Castle was nicknamed ‘The Showplace of Wales’ and attracted nearly ten million visitors.
Between 1968 and 1989 the Castle had many owners and many different uses. Gwrych finally closed to the public during the winter of 1985, never to reopen. Up until 2005, the weather, heartless vandals and New-age travelers had looted and ravaged the building to the point of near dereliction. Recent photos make it clear that large parts are no more than roofless shells. Since then, there have been efforts to consolidate the building and the current owners hope to convert it into a luxury hotel.
While travelling to Conwy to see the castle there, I saw from my car a huge unknown castle on a hillside – which I eventually identified as Gwrych, near Abergele. My schedule did not permit me to investigate further on the return leg of my trip, but you can find out more here: http://www.gwrychtrust.co.uk/index.html The Gwrych Castle Preservation Trust would welcome your support. This is a sad example of what can happen to a historic listed building when its owners run out of cash. For obvious reasons you cannot visit the castle, but the Gwrych preservation trust claim there are public rights of way through the estate (disputed in comment). Anyway, Google Streetview indicates that the A547 runs within yards of the castle outer wall and gates. (pic Wikimedia, CC-SA, Dot Potter)
