The Senedd (English: Legislature, Parliament or Senate; Welsh pronunciation: [ˈsɛnɛð]), also known as the National Assembly building, houses the debating chamber and three committee rooms for the National Assembly for Wales in Cardiff. The 5,308 square metres (57,100 sq ft) Senedd building was opened by Queen Elizabeth II on 1 March 2006 and the total cost was £69.6 million, which included £49.7M in construction costs. The Senedd is part of the National Assembly complex that includes Tŷ Hywel and the Pierhead Building. After two selection processes, the decision was taken that the debating chamber would be on a new site, called Site 1E, at Capital Waterside in Cardiff Bay. The Pritzker Prize-winning architect Richard Rogers won the international competition to design the building. It was designed to be sustainable with use of renewable technologies and be energy efficient. The building was awarded an "Excellent" certification by the Building Research Establishment Environmental Assessment Method (BREEAM), the highest ever awarded in Wales, and was nominated for the 2006 Stirling Prize.

Cardiff is home to the Welsh government in Cardiff Bay and much of the media in Wales. Doctor Who and Torchwood along with other television series are filmed mostly within the City and County of Cardiff. It has the biggest media sector in the UK outside London, being home to several television studios and radio stations. It was a small town until the early 19th century and came to prominence as a major port for the transport of coal following the arrival of industry in the region. Cardiff was made a city in 1905, and proclaimed capital of Wales in 1955.
