We have never previously been to the National Slate Museum close to Llamberis – in fact, shamefully, I didn’t know of its existence.

It’s magnificent.  It occupies the workshops of the Dinorwic Slate Quarry, closed in 1969, reopened in 1972, so able to keep many of the workshops with the signage and equipment intact.

This is the entrance front, dated 1870, rather Eastern European in feel:-

The remains of the Quarry looms above:-

Old signage:-

The Power Hall:-

Through to the Foundry:-

To the blacksmith’s forge:-

Tools of the trade:-

It is the most evocative site of industrial archaeology I’ve been to since I first visited the Whitechapel Bell Foundry in February 2017.
