Cardiff (; Welsh: Caerdydd [kairˈdiːð, kaːɨrˈdɨːð] (listen)) is the capital and largest city of Wales. It forms a principal area, officially known as the City and County of Cardiff (Welsh: Dinas a Sir Caerdydd), and the city is the eleventh-largest in the United Kingdom. Located in the south-east 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. Cardiff Built-up 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. At the 2011 census, the unitary authority area population was put at 346,090, and the wider urban area at 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.Cardiff is a major centre for television and film production (such as Doctor Who, Torchwood and Sherlock) and is the Welsh base for the main national broadcasters. Cardiff Bay contains the Senedd building (housing the Senedd, the Welsh Parliament) and the Wales Millennium Centre arts complex. Work continues at Cardiff Bay and in the centre, on projects such as Cardiff International Sports Village, BBC drama village, and a new business district.

Cardiff's town walls were a Medieval defensive wall enclosing much of the present day centre of Cardiff, the capital city of Wales, which included Cardiff Castle. It measured 1280 paces or 1.280 miles (2.060 kilometres) in circumference and had an average thickness of between 6 feet (1.8 metres) and 8 ft (2.4 m) and a height of 10 ft (3.0 m). It had five town gates and was first mentioned in the year 1111. Sections of the wall collapsed in the 18th century due to neglect, and many stones were then used as building material for other buildings in the town. The last large section of the wall was demolished in 1901. Now there are only two sections of the Medieval wall that still remain. One section of the wall supports a flower bed to the east of Cardiff Castle on Kingsway, and the second, larger section forms the rear of a shop on Queen Street in an unmarked alleyway immediately on the other side of Kingsway, between the Northgate Building and One Kingsway.

St. John's Gardens (Welsh: Gerddi Sant Ioan) are a small public garden in the center of the Welsh capital Cardiff in United Kingdom. It is located between St John's Church and the Old Library. The park is around 1000 m² in size and is enclosed by cast iron railings. The gardens have some old trees (including a large magnolia tree), some flower beds, a central hut and several benches. Originally part of the graveyard of St John's Church, which stretched south from the church to the library building, the area was separated when the Cardiff Corporation built a public path between Working Street and Cardiff Central Market during the 1890s. As part of the agreement with the church, the Corporation agreed to take responsibility for the area which is now St John's Gardens. The Gardens still contain tombs and gravestones. The railings and gates (dating from the 1890s) are Grade II listed. The wooden hut at the centre of the gardens is also Grade II listed.The gardens were closed for six months in 2018 because of anti-social behaviour in the area.

The Cardiff district (Welsh: Caerdydd) was one of the two local government districts of South Glamorgan in Wales from 1974 to 1996. The district comprised the area of the former county borough of Cardiff and several surrounding parishes. Letters patent continuing the city status of the county borough were granted on 1 April 1974. The district was therefore styled the City of Cardiff, governed by Cardiff City Council. The district was formed by the Local Government Act 1972, from the county borough of Cardiff, the parishes of Lisvane, Llanedeyrn, Radyr, St. Fagans and Tongwynlais from the former Cardiff Rural district in the administrative county of Glamorgan and the parish of St Mellons from the Magor and St Mellons Rural District in the administrative county of Monmouthshire.The district was abolished in 1996 by the Local Government (Wales) Act 1994, when it was reconstituted, with the addition of Pentyrch, as the City and County of Cardiff.
