Moelwyn Quarry
From Festipedia, hosted by the FR Heritage Group
This slate quarry, originally opened in the 1820's from several small levels on the eastern face of Moelwyn Bach. The development and linking of Moelwyn Mawr and Bach quarries by incline at Cwm Stwlan was an attempt by Baron Rothschild to lay claim, on behalf of the Crown, to the mineral wealth of the Principality. In the 1860s it was developed underground on the southern flank of Moelwyn Mawr. Active in the 1870s and again in the 1890s, it closed about 1900. In the early 1860s the quarry was connected to the Festiniog Railway by the spectacular incline sysytem which remains today (though is broken at Cwm Stwlan, site of Stwlan Dam).
