Was there a Slate works in Liverpool during the 1800s?
Slate is Mined or quarried not made. Bleneu Ffestiniog in North Wales was the major producer of slate which was exported out of Portmadog. You can get the steam railway out of Portmadog, up too Ffestiniog its a stunning line and Ffestiniog has massive slate slag heaps all around the town. So there would have been somewhere that slate was distributed for house building in Liverpool, but there was no quarry. The main quarry in Liverpool is in Woolton at Quarry St, but that was sandstone. Edit At that time there was a big influx of Welsh workers into Liverpool, it is said that Liverpool was built by the Welsh. there was a big Welsh community in the Dingle, and some historians have claimed that at the turn of the century more Welsh was spoke in Liverpool than in Wales.
