Inigo Jones Slate Works was founded in 1861 mainly to prefabricate school writing slates. Today the company uses the same raw material namely 500 million year old Welsh slate to produce architectural, memorial, landscape and craft products.
The slate in this mine, which is found in veins between layers of ancient Pre-Cambrian rocks, is among the oldest in the world. Many industrial towns in Britain and Ireland have the original roofs made of Llanfair slate.
Set in seven acres of grounds, overlooking the Isle of Anglesey, Plas Menai is open all year around and is the perfect destination for anybody looking for outstanding watersports and outdoor adventure.
Porthmadog’s bustling harbour was even busier 150 years ago. Discover the reason at this museum, which tells the story of the port’s shipbuilding and slate exporting heyday.
