Tower Colliery
Tower Colliery (Welsh: Glofa Tŵr) was the oldest continuously working deep-coal mine in the United Kingdom, and possibly the world, and the last mine of its kind to remain in the South Wales Valleys. It was located near the villages of Hirwaun and Rhigos, north of the town of Aberdare in the Cynon Valley south Wales.
==History==
With coal located so close to the surface, it was known by locals to be possible to drift mine coal from Hirwaun common. This activity increased from 1805, until in 1864 the first drift named Tower was started, named after the nearby Crawshay's Tower, a folly built in 1848 and named after Richard Crawshay.〔http://www1c.btwebworld.com/tower-coal/tmenu.html〕
In 1941, a new shaft was sunk to a depth of 160 metres. From 1943 until closure, this shaft was used as the main "return" ventilation shaft and for the transport of men. In 1958 Tower No. 3 was driven to meet the No. 4 colliery workings, and was used as the main "intake" airway, conveying coal to the surface and transporting materials into the mine working areas.〔
The Aberdare branch of the Merthyr line continued north from Aberdare railway station to the colliery. While passenger services terminate in Aberdare, freight services operated several times a day along this stretch of line, directly owned by the colliery.
