decline of industry

Through the 20th century, heavy industries in the town declined, leaving the Lower Swansea Valley filled with derelict works and mounds of waste products from them. The Lower Swansea Valley Scheme (which still continues) reclaimed much of the land. The present Enterprise Zone was the result and, of the many original docks, only those outside the city continue to work as docks; North Dock is now Parc Tawe and South Dock became the Marina.
