Moelwyn quarry is a defunct slate quarry located to the south of the village of Tanygrisiau, north Wales. Some initial prospecting was carried out in the 1820s and again in the 1840s, but it was 1860 before a company was formed, and chambers were excavated. The quarry was never a financial success, and operated sporadically until its demise in 1897. Despite the poor results, a spectacular series of seven inclines were constructed, to enable slates to reach the Ffestiniog Railway. The quarry was hampered by lack of a good water supply, and the mill was constructed between inclines 4 and 5, where water could be obtained from Llyn Stwlan. As in many quarries, barracks were provided, but these were occupied by whole families, living on the mountain, rather than used as lodgings for the quarrymen during the working week. Even in its remote location, there was still a concern for education, with basic literacy classes being run in the 1860s.
Fron-Boeth and Pant Mawr quarries were two closely related and interconnected quarries on the western slopes of Moelwyn Mawr in Gwynedd, North Wales. Pant Mawr operated from around 1850 to 1879, and was partly re-opened in 1886 when it was amalgamated with Fron-Boeth. Both quarries closed during the First World War. Finished product was transported to the slate quays of Porthmadog by the Croesor Tramway.
