Information

The south-western aspect of Elidir Fawr, above the lake Llyn Peris and the town of Llanberis, is dominated by the sculpted landscape formed by the now quiet galleries of Dinorwic Quarry. Commercial quarrying of slate started there in 1787 and production continued until the business closed in 1969.

The quarry was originally part of the Vaynol Estate, owned by the Assheton Smith family. It was once the second largest slate quarry in the world, after the nearby Penrhyn Quarry. At its peak in the late 19th century, it employed 3,000 quarrymen and produced 100,000 tonnes of finished slate a year. Slates were exported from the quay at Port Dinorwic (Y Felinheli) and a tramway from the quarry to the port was constructed in 1824. This was superseded in 1842 by the Padarn Railway.

When the quarry closed, its workshops at Gilfach Ddu were acquired by the National Museum of Wales and are now home to the National Slate Museum. The quarry itself is now owned by First Hydro, operators of Dinorwig Power Station. This pumped-storage hydroelectricity plant uses Llyn Peris as its lower reservoir and Marchlyn Mawr as its upper one. The power station was completed in 1984, having taken 10 years to construct. It is housed deep inside Elidir mountain itself and its Machine Hall is the largest man-made cavern in Europe. There are 16 km of underground tunnels and the total volume of rock excavated from underground amounted to 1 million cubic metres (3 million tonnes).

Information

With an elevation of 1044 m, Carnedd Dafydd is the fourth highest peak in Wales (when Garnedd Ugain in the Snowdon massif is included). The name of the mountain means David’s Cairn, probably in honour of Dafydd ap Gruffudd, younger brother of the last independent prince of Wales, Llywelyn ap Gruffudd. Dafydd was captured in 1283 and taken to Shrewsbury where he was hanged, drawn and quartered.

Information

On the slopes of Cefn Du, in a fairly narrow band extending from the roadside of the A4086 through Llanberis up to the coll with Moel Eilio, there can be found a number of disused slate quarries. Starting from the bottom, these are: Glyn Rhonwy Isaf (with three pits), Glyn Rhonwy Uchaf (two pits), Cook and Ddol (two pits), Cefn Du and, finally, Chwarel Fawr. Quarrying operations in this area date back to the end of the 18th century and had ceased by 1930.

In 1939 the Air Ministry converted the lower pit of Glyn Rhonwy Isaf into a storage facility with a capacity for 18,000 tons of bombs. The store was constructed with two levels, the pit being backfilled with broken slate to a depth of 40 feet over the top of the roof of the upper level. Unfortunately, skimping on costs led to structural defects which caused a massive collapse of about two thirds of the building only six months after it had been built. A train, laden with a bomb payload in excess of 14,000 tons, was in the depot at the time of the collapse. The remaining underground section was thereafter abandoned and the collapsed area used for open storage. The facility was closed in 1956 but was not fully cleared of all explosive material until 1975.

Gwynedd Council owns the land comprising the former Glyn Rhonwy (Isaf and Uchaf) and Cook and Ddol Quarries, and has, for a number of years, been seeking to attract developers to the site. A land reclamation project in the lower parcel of the site (comprising the former Glyn Rhonwy Isaf Quarry) was completed in 2000, which included building an access road and creating various development plateaux. Further clearing of the site and upgrading the infrastructure with the aim of enticing investment is still underway.

Various ambitious schemes for the site have fallen through in the past – including plans in 2002 and 2003 for an indoor snow dome. In 2006 the Guardian reported that eight business groups were competing to develop the site, with one scheme including plans for a ski run, beach, spa, climbing wall, hotel, apartments and timeshares, and another with plans for a mountain bike centre featuring a mile-long cable car ride over the quarries. In 2009 Manchester-based consultancy DTZ put forward details of a scheme for mixed-use development, including business units, residential areas, outdoor leisure businesses and a campsite and caravan park.

An area originally part of the Glyn Rhonwy redevelopment site was sold in 1985 and is occupied by the Siemens Healthcare Diagnostics biotech plant (formerly Euro/DPC).

Glyn Rhonwy was used as a location in the making of the 1988 Ron Howard film Willow.
