Cardiff Bay Opera House
Cardiff Bay Opera House was a proposed centre for the performing arts in Cardiff Bay, Cardiff, Wales, conceived in the 1990s as a crucial part of the Cardiff Bay redevelopment project. One aim of the scheme was to create a new home for the Welsh National Opera company, which was then based in the New Theatre in Cardiff. The Wales Millennium Centre was built in its place and it opened in 2004. The plan, supported by the Cardiff Bay Development Corporation, was to construct a permanent home for Welsh National Opera on a site near the Inner Harbour, Cardiff Bay. An international design competition was held and was eventually won by the Iraqi-born architect Zaha Hadid. The Hadid design was called the Crystal Necklace by some in the media. However, the project failed to win financial support from the Millennium Commission, the body which distributed funds from the UK National Lottery.

Cardiff
Cardiff ( ; Welsh: Caerdydd [kairˈdiːð, kaːɨrˈdɨːð] ) is the capital and largest city of Wales. Cardiff had a population of 383,919 in 2024 and forms a principal area officially known as the City and County of Cardiff (Welsh: Dinas a Sir Caerdydd). The city is the eleventh largest in the United Kingdom. Located in the southeast of Wales and in the Cardiff Capital Region, Cardiff is the county town of the historic county of Glamorgan and in 1974–1996 of South Glamorgan. It belongs to the Eurocities network of the largest European cities. A small town until the early 19th century, its prominence as a port for coal when mining began in the region helped its expansion. In 1905, it was ranked as a city and in 1955 proclaimed capital of Wales. The Cardiff urban area covers a larger area outside the county boundary, including the towns of Dinas Powys and Penarth. Cardiff is the main commercial centre of Wales as well as the base for the Senedd, the Welsh Parliament. At the 2021 census, the unitary authority area population was put at 362,400. The population of the wider urban area in 2011 was 479,000. In 2011, it ranked sixth in the world in a National Geographic magazine list of alternative tourist destinations. It is the most popular destination in Wales with 21.3 million visitors in 2017. It was voted as the best city in the UK at the 2023 Readers' Choice Awards. Cardiff is a major centre for television and film production (such as the 2005 revival of Doctor Who, Torchwood and Sherlock) and is the Welsh base for the main national broadcasters. Cardiff Bay contains the Senedd building and the Wales Millennium Centre arts complex.
