Its slate went to Germany and exists there today on the roofs of thousands of dwellings, as well as to America, where the Boston Court House is roofed with Welsh slate. The slate often travelled in Porthmadog-built vessels – over 200 sailing ships were built in Porthmadog between 1830 and 1914. The Moelwyn mountains' mines, which held the world's largest deposit of slate, employed around 3,000 men in the nineteenth century. In the 1830s, the Festiniog Railway Company was formed, in order to carry slate between Blaenau and Porthmadog harbour, leading to the development of the famous 'Double Fairlie' locomotive there. Using a wonderful collection of images and drawing on his background in the area, John Idris Jones explores the fascinating history of these industries. Born in the remote Welsh-speaking village of Llanrhaiadr-ym-Mochnant in mid-Wales, the author as a child spent many months at his grandparents' house in Borth-y-Gest, near Porthmadog. Here he witnessed the active port, the remains of the slate industry and the Ffestiniog Railway.
