The current capital of Wales is Cardiff. Historically, Wales did not have a definite capital. In 1955, the Minister for Welsh Affairs informally proclaimed Cardiff to be the capital of Wales. Since 1964, Cardiff has been home to government offices for Wales, and since 1999 it has been the seat of the Senedd Cymru - Welsh Parliament.
History
In the past, multiple places have served as a seat of the government of Wales, including:
The ecclesiastical capital of Wales is St Davids, the resting place of the country's patron saint, Saint David. In the 19th century, Cardiff grew to become the largest settlement in Wales, due to its role as a port for exporting coal from the South Wales Valleys. By 1881, it had overtaken both Swansea and Merthyr Tydfil to become the country's largest city. In 1905, Cardiff received city status. In subsequent years, an increasing number of Welsh national institutions were founded in the city, including the National Museum of Wales, Welsh National War Memorial, and the University of WalesRegistry Building. However, the National Library of Wales would instead be located in Aberystwyth, where it remains to this day. This was partly because the library's founder, Sir John Williams, did not think that Cardiff was a Welsh city in character. In 1911, the tradition of holding an investiture of the Prince of Wales was revived, and took place in Caernarfon. In the 20th century, Welsh local authorities debated where a new capital of Wales should be, with 76 out of 161 opting for Cardiff in a 1924 poll, organised by the South Wales Daily News. The authorities were mostly split between Cardiff and Caernarfon, with a smaller faction supporting Aberystwyth. The discussions stalled and progress was not made until 1950.
Recognition of Cardiff
The government of the Labour Prime Minister, Clement Attlee, had not named a capital of Wales during his government. Attlee noted that a number of cities made claims to the status, and that the Council for Wales and Monmouthshire did not raise what he considered to be a "domestic issue" with the Government. In his inaugural speech as Lord Mayor of Cardiff, George Williams argued that Cardiff should be considered the capital of Wales. David Llewellyn was elected MP for Cardiff North in 1950 and also campaigned for recognising Cardiff. Campaigning for Cardiff stepped up and the city took steps to promote its 'Welshness'. The stalemate over which city should be the new capital was broken when Cardiganshire County Council decided to support Cardiff and, in a 1955 poll of local authorities, 134 out of 161 voted for the city. On 20 December 1955, Gwilym Lloyd-George, then Minister for Welsh Affairs and Home Secretary, proclaimed that Cardiff was the capital of Wales, in a reply to a question from David Llewellyn. Lloyd-George said that "no formal measures are necessary to give effect to this decision" The Encyclopedia of Wales says that the decision to recognise the city as the capital of Wales "had more to do with the fact that it contained marginal Conservative constituencies than any reasoned view of what functions a Welsh capital should have".
Government institutions
Cardiff only became a centre of national administration with the establishment of the Welsh Office in 1964, which later prompted the creation of various other public bodies such as the Arts Council of Wales and the Welsh Development Agency, most of which were based in Cardiff. In a 1997 referendum, Wales narrowly voted in favour of establishing a National Assembly for Wales, although only 44% supported the proposal in Cardiff. Due to the relative lack of support for the Assembly locally, and disagreements between the Welsh Office and Cardiff Council over where it should sit, there was a brief period of speculation that the Assembly would be established elsewhere. However, the Assembly eventually located at Tŷ Hywel in Cardiff Bay in 1999. It has been based there ever since, moving to its present building in 2005.
