About Llechwedd Slate Caverns

The Llechwedd slate quarry was opened in 1846 by John Whitehead Greaves, a successful quarry owner.  In 1851, 2,900 tons of finished slate was produced by Llechwedd and the Ffestiniog Railway was extended to meet the quarry.  The 1960s saw a steep fall in the demand for slate.  Llechwedd turned their attention to other potential sources of revenue, and in 1972 opened the Llechwedd Slate Caverns tourist attraction.
