Inigo Jones Slateworks
Since 1861 slate has been shaped and shipped from here, but it's a safe bet they made less garden ornaments, placemats and picture frames back then. Before you get laden down with what's perhaps the ultimate North Welsh souvenir, you can take a self-guided tour of the works. The on-site cafe makes great Welsh cakes. It's on the A487, 5 miles south of Caernarfon.
