Scope and Content
Administrative / Biographical History
Dorothea Quarry was opened in 1820 and was located in the parish of Llandwrog, close to Talysarn, Caernarfonshire. The quarry was owned by John Williams of Plas Yn Blaenau, Llanrwst, Denbighshire. In 1848 John Jones of Talysarn (1796-1857), a Calvinistic Methodist minister, with some of his associates, bought the quarry from Williams. Unfortunately the slate industry went into decline during this period, and the quarrymen's wages were cut. Jones's eldest son, John Lloyd Jones (1826-1893) from Plas y Bryn, Bontnewydd, became one of the chief managers of Dorothea and Penyrorsedd Quarries. By 1879 Hugh Hughes and Nathaniel Jones were two of the owners of the quarry. The Dorothea Slate Quarry Co. Ltd operated during the late 19th and 20th centuries and had offices in Caernarfon; it was a member of North Wales Slate Quarries Association. During this time, the company leased land on the Pant Du estate, Llandwrog. Following the steady decline in the slate industry in Wales, the Dorothea Slate Quarry Co. Ltd entered liquidation in 1970, and the quarry was closed in 1971.
