had arrived in the 1830s. As the century progressed the canals gave way to the railways and the area became dissected by a network of railway lines carried on a series of multi-arch viaducts. Though Castlefield did have cotton mills, it was the engineering works and warehousing that was more noticeable. The first canal warehouse, built in 1771 on Coal Wharf, was used to raise coal from the barges to street level, and store other goods. In the nineteenth century the warehouses assumed other functions such as trans-shipment which involved receiving trains or barges, and reassembling their loads to be shipped to other destinations. Other warehouses received raw materials such as yarn, which was collected by outworkers who then returned woven cloth. The later warehouses acted as showrooms on the ground floors, with offices and storage above and behind. 20th century During the 20th century both canal and railway transport declined and the area became somewhat derelict. The railway complex in Liverpool Road was sold to a conservation group for a nominal £1 and became the Greater Manchester Museum of Science and Industry. In 1982 the area was designated as an urban heritage park and a part of the fort was reconstructed on the excavated foundations. Present day As part of the renewal of the site, an extensive outdoor area was developed as an events arena which is used for a wide variety of events, including the annual 'Dpercussion' music festival. Granada Television studios are located in the area along with the now closed Granada Studios Tour. In 2008 it was reported that ITV were considering re-opening the tour as the company is searching for new forms of revenue to restore growth. Castlefield has several bars and restaurants which are particularly popular during the summer months when people flock to the area to enjoy the large outdoor drinking areas and regular live music events. The popular Barça Bar closed in late December 2008, leaving Dukes 92, Choice Bar & Restaurant and Lava Bar as the only bars within the Castlefield basin. Castle Quay is the home of radio stations Hits Radio (formerly Key 103) and Greatest Hits Radio.

In 2011, planning permission was rejected again by Manchester City Council with opposition from
