Cardiff is the county town of the historic county of Glamorgan, and, between 1974 and 1996, South Glamorgan. Cardiff is part of the Eurocities network of the largest European cities. A small town until the early 19th century, its prominence as a major port for the transport of coal following the arrival of industry in the region contributed to its rise as a major city. In 1905, Cardiff was made a city. In 1955, it was proclaimed the capital of Wales. In the 2011 Census, the population was 346,100. The Cardiff Built-up Area covers a slightly larger area outside the county boundary and includes the towns of Dinas Powys and Penarth.
