I know people love the underground areas of Maenofferen however on this trip I kept above ground, maybe one day I'll go back and tackle the underground workings but if I'm honest it's the above ground industrial stuff here that's always tickled my fancy more as personally I find it more interesting, but that's just me.

The quarry was first staffed by men from the nearby Diphwys quarry shortly after 1800. Come 1848 the slate was being shipped via the Ffestiniog Railway. This was short lived, and this service ceased in 1850. Traffic resumed in 1857 and apart from a gap in 1865; there remained a steady flow of slate dispatched via the railway.

In 1861 the Maenofferen Slate Quarry Co. Ltd. became incorporated, producing approximately 400 tons of slate in that year.

During the 1800s the quarry flourished and expanded, extending its workings underground and further downhill towards Blaenau Ffestiniog.

By the year 1897 it employed 429 people with almost half of those men working underground. Eventually, 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.

Llechwedd Quarry purchased Maenofferen in 1975 together with Bowydd. Underground production of slate ceased during November 1999 and signalled the end of large-scale underground working for slate in North Wales.
Anyone who's been here knows that 'the walk' up to the top of the quarry to get to these buildings is pretty arduous, the gradient is steep and the surface not ideal and it's just as hard coming down as well! The hike up the quarry is totally worth it however for anyone who likes old industry as the cutting sheds and associated buildings are in a wonderful state of decay, the marathon hike seemingly too much for the local morons to bother with. We spent a good couple of hours up top but in reality could have spent much longer, sadly we realised time was rapidly running out on us and given the length of the walk down the quarry and how much more we had to see before heading home, made tracks to leave.

And to finish a few from the long walk down....

Thanks for looking :)​
