In the early part of the 19th century Welsh coal was in much demand throughout the world. Cardiff was the centre of this export trade, but it was under the control of the Bute family. In 1859, the Taff Vale Railway Company created a series of wharves in the mouth of the river Ely. By 1898 the site had a chain ferry (right) which gave Ferry Road its name. A subway was also created for dockers to travel to the site.
