English: Rhosydd Quarry (quarry), at the head of Cwmorthin glacial valley, Blaenau Ffestiniog, Gwynedd. Rhosydd quarry is a disused slate quarry northeast of Porthmadog, Wales.
Small-scale working of the site began in the 1830s, but was hampered by the remote location, and the lack of a transport system to carry the slates to markets. The Rhosydd Slate Company was formed in 1853, and became a limited company in 1856. Transport was made more difficult by the attitude of the Cwmorthin quarry, through whose land the most obvious route to the Ffestiniog Railway ran. A solution was found in 1864, with the opening of the Croesor Tramway, to which the quarry was connected by one of the longest single-pitch cable-hauled inclines in Wales. Huge amounts of money were spent on development work, and the company, unable to make adequate returns, went into voluntary liquidation in 1873. The quarry was auctioned in 1874, and the New Rhosydd Slate Quarry Company Ltd. was formed. More on Wikipedia. |
