While conservation and redevelopment work take place at the Museum, we’re taking our people, collections and stories on the road to locations at the heart of the slate story. During this time you can come and see us at the following locations at the heart of the slate story:

Penrhyn Castle, Llandygai Bangor LL57 4HT

The Forge@CeiLlechi Cei Llechi Caernarfon LL55 2PB

Quarry Hospital Parc Padarn Llanberis LL55 4TY

Our museums are free to enter and open to everyone, making them places to visit again and again over the summer. There’s always something new to explore, and endless opportunities to create memories with family, friends or enjoy on your own. 

We recommend checking opening times before your visit. Entry to Quarry Hospital and Cei Llechi is free. Standard National Trust admission charges apply at Penrhyn Castle.

Start your Summer of Fun with us and see where it takes you.
