the soaring worldwide demand for south Wales coal. By 1907 Cardiff's docks had of quayage, one of the largest dock systems in the world at that time. Cardiff's port, known as Tiger Bay, became - for some time - the world's most important coal port, and for a few years before World War I the tonnage handled at the port outstripped London and Liverpool (however, some statistical tables conflate Barry and Penarth trade figures with Cardiff's, so the role of the coal port can be inflated). In 1907, Cardiff's Coal Exchange was the first host to a business deal for a million pounds Sterling. Competition from the new docks at Barry from the 1890s, and falling demand for Welsh coal during the interwar period, contributed to the decline of the port. By the 1980s large areas of Cardiff docks were derelict, and a regeneration project that eventually transformed South Cardiff began. Steel The construction of the East Moors Steelworks, known as 'Dowlais by the Sea', established Cardiff as a major steelmaking centre in the 1890s and was the first example of the Welsh industry's move from inland to coastal locations. The plant's main products were steel plates for shipbuilding (though it did not provide the hoped-for stimulus for a local shipbuilding industry) and by the 1930s it was manufacturing half a million tons of steel per year. Although the East Moors works closed in 1978, steel production continues in Cardiff at the Celsa Steel UK plant in Cardiff Bay, which produces reinforcing bars and wire. Retail Retail also plays a strong role in the city's employment, with it being listed as being the 6th best place to shop in the UK according to recent surveys. The majority of Cardiff's shopping portfolio is in the city centre around Queen Street and St. Mary's Street. There are also numerous suburban retail parks serving the city. Cardiff retail sector is dominated by three main shopping arcades located in the city centre; St. David's Centre, Queens Arcade and the Capitol Centre. The current expansion of St. David's Centre as part of the St. David's 2 project is allowing a huge piece of land between The Hayes and Charles Street to be demolished and redeveloped, bringing around 200 shops, flats and a John Lewis department store to the city. This will more than double the available floor space, making it one of the largest shopping
