Maenofferen quarry [1] (also known as Maen Offeren quarry [2] ) is a major slate quarry in the town of Blaenau Ffestiniog, north Wales and one of the major users of the Ffestiniog Railway. It continues to produce crushed slate on a limited scale under the ownership of the nearby Llechwedd quarry.
Maenofferen was first worked for slate by men from the nearby Diphwys quarry shortly after 1800. By 1848 slate was being shipped via the Ffestiniog Railway, but traffic on the railway ceased in 1850. In 1857 traffic resumed briefly and apart from a gap in 1865, a steady flow of slate was dispatched via the railway. The initial quarry on the site was known as the David Jones quarry which was the highest and most easterly of what became the extensive Maenofferen complex.
In 1861 the Maenofferen Slate Quarry Co. Ltd. was incorporated, led by Sir William Fothergill Cooke and Mr. Veasey. [3] The quarry produced around 400 tons of slate that year. The company leased a wharf at Porthmadog in 1862 and shipped 181 tons of finished slate over the Ffestiniog Railway the following year.
During the nineteenth century the quarry flourished and expanded, extending its workings underground and further downhill towards Blaenau Ffestiniog. By 1897 it employed 429 people with almost half of those working underground. The Ffestiniog Railway remained the quarry's major transport outlet for its products, but there was no direct connection from it to the Ffestiniog's terminus at Duffws. Instead slate was sent via the Rhiwbach Tramway which ran through the quarry. This incurred extra shipping costs that rival quarries did not have to bear.
In 1908 the company leased wharf space at Minffordd, installing turntables and siding to allow finished slates to be transshipped to the standard gauge railway there.
In 1920 the company solved its high shipping costs by building a new incline connecting its mill to the Votty & Bowydd quarry and reaching agreement to ship its products via that company's incline connection to the Ffestiniog Railway at Duffws.
In 1928 Maenofferen purchased the Rhiwbach quarry, continuing to work it and use its associated Tramway until 1953.
When the Ffestiniog Railway ceased operation in 1946, Maenofferen leased a short length of the railway's tracks between Duffws station and the interchange with the LMS railway, west of Blaenau Ffestiniog. Slate trains continued to run over this section until 1962, Maenofferen then becoming the last slate quarry to use any part of the Ffestiniog Railway's route. From 1962 slate was shipped from the quarry by road, although the internal quarry tramways including stretches of the Rhiwbach tramway continued in use until at least the 1980s.
The quarry was purchased by the nearby Llechwedd quarry in 1975 together with Bowydd, which also incorporated the old Votty workings: these are owned by the Maenofferen Company. Underground production at Maenofferen ceased during November 1999 and with it the end of large-scale underground working for slate in north Wales. Production of slate recommenced on the combined Maenofferen site, consisting of "untopping" underground workings to recover slate from the supporting pillars of the chambers. Material recovered from the quarry tips will also be recovered for crushing and subsequent use.

Blaenau Ffestiniog is a town in Gwynedd, Wales. Once a slate mining centre in historic Merionethshire, it now relies much on tourists, drawn for instance to the Ffestiniog Railway and Llechwedd Slate Caverns. It reached a population of 12,000 at the peak development of the slate industry, but fell with the decline in demand for slate. The population of the community, including the nearby village Llan Ffestiniog, was 4,875 in the 2011 census: the fourth most populous in Gwynedd after Bangor, Caernarfon and Llandeiniolen. The population not including Llan is now only about 4,000.
The slate industry is the industry related to the extraction and processing of slate. Slate is either quarried from a slate quarry or reached by tunneling in a slate mine. Common uses for slate include as a roofing material, a flooring material, gravestones and memorial tablets, and for electrical insulation.
The existence of a slate industry in Wales is attested since the Roman period, when slate was used to roof the fort at Segontium, now Caernarfon. The slate industry grew slowly until the early 18th century, then expanded rapidly until the late 19th century, at which time the most important slate producing areas were in northwest Wales, including the Penrhyn Quarry near Bethesda, the Dinorwic Quarry near Llanberis, the Nantlle Valley quarries, and Blaenau Ffestiniog, where the slate was mined rather than quarried. Penrhyn and Dinorwig were the two largest slate quarries in the world, and the Oakeley mine at Blaenau Ffestiniog was the largest slate mine in the world. Slate is mainly used for roofing, but is also produced as thicker slab for a variety of uses including flooring, worktops and headstones.
The Rhiwbach Tramway was a Welsh industrial, 1 ft 11+1⁄2 in narrow gauge railway connecting the remote slate quarries east of Blaenau Ffestiniog with the Ffestiniog Railway. It was in use by 1862, and remained so until progressively closed between 1956 and 1976. The route included three inclines, one of which became the last operational gravity incline in the North Wales slate industry. The tramway was worked by horses and gravity for much of its existence, but a diesel locomotive was used to haul wagons on the top section between 1953 and its closure in 1961.
Llechwedd quarry is a major slate quarry in the town of Blaenau Ffestiniog, north Wales. At its peak in 1884 it produced 23,788 tons of finished slate per year and had 513 employees. It continues to produce slate on a limited scale and is the location of the Llechwedd Slate Caverns tourist attraction.
Tan-y-Manod railway station was a railway station approximately 1 mile (1.6 km) south of Blaenau Ffestiniog, in Gwynedd, North Wales.
Rhosydd quarry was a slate quarry in the Moelwyn mountains, northeast of Porthmadog in North Wales.
Oakeley quarry is a slate quarry in the town of Blaenau Ffestiniog, north Wales. It was the largest underground slate mine in the world, and had 26 floors spanning a vertical height of nearly 1,500 feet (460 m).
The Cwt y Bugail quarry is a former slate quarry located east of Blaenau Ffestiniog in Wales. It was first worked as a trial pit around 1840. Continuous production began in 1863 and continued until closure in 1961. The quarry was connected to the Ffestiniog Railway at Duffws Station via the Rhiwbach Tramway.
The Blaen y Cwm quarry was a slate quarry located east of Blaenau Ffestiniog in Wales. It was first worked in some time between 1813 and 1818 and sporadically after that until 1914. The quarry was connected to the Ffestiniog Railway at Duffws Station via the Rhiwbach Tramway.
Rhiwbach quarry was a slate quarry located to the east of Blaenau Ffestiniog in North Wales. The quarry was a remote site; it was nearly 4 miles (6.4 km) to north-east of Duffws, the Festiniog Railway's terminus in Blaenau Ffestiniog. It was the connected to the Ffestiniog Railway by the Rhiwbach Tramway. Commercial operation began around 1812, and it finally closed in 1952. It was the last Welsh slate quarry where workers lived in barracks on the site. 'Rhiwbach' is Welsh for 'Little Hill'.
Cwmorthin quarry was a slate quarry west of the village of Tanygrisiau, north Wales. Quarrying on the site started in 1810. In 1860 it was connected to the Ffestiniog Railway. In 1900 it was acquired by the nearby Oakeley quarry and the two were connected underground. In 1970 it closed along with Oakeley. There was small-scale working in the 1980s and 1990s, and the mine finally closed in 1997.
Votty & Bowydd quarry is a major slate quarry in the town of Blaenau Ffestiniog, North Wales. It was one of the major users of the Ffestiniog Railway. It opened in 1870 In the quarry's peak years around 1900, the quarry produced around 17,000 tons-per-annum of slate, employing 500 men. It continues to produce crushed slate on a limited scale under the ownership of the nearby Llechwedd quarry.
Diphwys Casson quarry was a major slate quarry in the town of Blaenau Ffestiniog, Gwynedd, North Wales. It was one of the major users of the Ffestiniog Railway.
Graig Ddu quarry is a disused slate quarry near Blaenau Ffestiniog, in Gwynedd, North Wales. Although output was only about 3,000 tons a year, it reputedly has 36 saw tables and the same number of dressing machines on site. As with others in the area, the quarry suffered from a lack of water, resulting in the siting of the mill some distance away, at a lower level.
Nyth-y-Gigfran quarry was a slate quarry in the town of Blaenau Ffestiniog, North Wales. It was located about 300 feet (91 m) above the settlement of Glan y Pwll, south of what was to become Blaenau Ffestiniog. The quarry was sited on the steep cliffs that form the eastern edge of Allt-fawr and was entirely underground. The quarry opened around 1840 and became part of the Oakeley quarry in the 1880s; this in turn closed in 1969.
The Cwmorthin Tramway was a 1 ft 11+1⁄2 in industrial tramway in North Wales, which connected the Ffestiniog Railway to the Cwmorthin Quarry and later the Conglog Slate Quarry. It was built in the 1840s or 1850s, rising through two inclined planes to reach the main Cwmorthin Quarry mill and its internal incline which rose from floor 1 to floor 8. In 1874, it was extended, rising up through a third incline to the Cwmorthin Lake level and continuing along the valley floor to reach the Conglog Quarry. The tracks to Conglog were abandoned in the 1920s and the rest of the tramway ceased to be used from the onset of the Second World War.
Dinas station was built by the Festiniog Railway (FR). It was the first passenger station in Blaenau Ffestiniog, then in Merionethshire, now in Gwynedd, Wales. This station is not to be confused with Dinas some miles distant on the Welsh Highland Railway; nor is it to be confused with the Festiniog and Blaenau Railway's northern terminus in the centre of Blaenau Ffestiniog which was sometimes referred to colloquially as "Dinas".
Blaenau Ffestiniog North was the London and North Western Railway's (LNWR's) second passenger station in Blaenau Ffestiniog, then in Merionethshire, now in Gwynedd, Wales.
