Cardiff is the capital and largest city of Wales. It forms a principal area, officially known as the City and County of Cardiff, 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. Cardiff Bay contains the Senedd building (home to the Senedd, the Welsh Parliament) and the Wales Millennium Centre arts complex.

These fascinating black and white photos were taken by Ben Salter that show how Cardiff has changed from the 1970s.
