In the 1720's, canals from the Rivers Irwell and Mersey allowed boats to go from Liverpool to Manchester bringing raw materials into Manchester, and taking away finished manufactured goods. The Duke of Bridgewater opened a canal in 1760, from the Worsley coal mines to Manchester, bringing in the coal needed for manufacturing and heating. Soon following, the Bolton and Bury Canal was developed to the Irwell River, and in 1804 the Rochdale Canal was linked the Bridgewater Canal to the existing system of canals to the east. With the extensive canal system in place, Manchester quickly became the center of a canal network linking Lancaster with London, and Liverpool with Hull. With the influx of the large scale river and canal warehouses, the Castlefield area developed very rapidly. In 1894 Queen Victoria opened the last and greatest development in the canal system, the Manchester Ship Canal. The new canal linked Manchester directly with the ocean. The Canal allowed ocean going vessel to travel thirty five miles into the heart of England to deliver their goods straight to Manchester.
