Swansea Canal

The Swansea Canal was a canal constructed by the Swansea Canal Navigation Company between 1794 and 1798, running for 16.5 miles from Swansea to Hen Neuadd, Abercraf in South Wales. It was steeply graded, and 36 locks were needed to enable it to rise 373 feet over its length. The main cargos were coal, iron and steel, and the enterprise was profitable.

Sold to the Great Western Railway in 1873, it continued to make a profit until 1895. A period of decline followed, with the last commercial traffic using the waterway in 1931. Subsequently, parts of it were closed and filled in under a succession of owners, but around 5 miles remain in water. The Swansea Canal Society, formed in 1981, is actively involved in plans for its restoration.
