The city of Cardiff, capital of Wales, United Kingdom

 "Castell Coch's external features and the High Victorian interiors led the historian David McLees to describe it as "one of the greatest Victorian triumphs of architectural composition."

=========================

(in Wales) The city of Cardiff, capital of Wales, is found on the Bristol Channel at the mouth of the Taff River. The Welsh capital may have originated as a Roman fort, but it has since become a bustling city. With many new and exciting things to see, the National History Museum is the most visited attraction in Wales. Featured here is Coch Castle, perched atop a thickly wooded crag on the northern fringes of Cardiff. It was the summer retreat of the third marquess of Bute and, like Cardiff Castle, was designed by architect William Burges in Gothic-revival style. Raised on the ruins of Gilbert de Clare's 13th-century Castell Coch (Red Castle), the Butes' onetime holiday home is another popular tourist destination in Wales. John Crichton-Stuart, the 3rd Marquess of Bute, inherited the castle in 1848. One of Britain's wealthiest men, with interests in architecture and antiquarian studies, he employed the architect William Burges to reconstruct the castle, "as a country residence for occasional occupation in the summer," using the medieval remains as a basis for the design.
