Mining has shaped the village of Altlay and its residents and given the village its name Altlay. In local dialect, a lay is a roofing slate. Anyone who visits the narrow stream valleys around Altlay will not fail to notice striking evidence of mining here and there. Here, at every turn, you come across the remains of what was once a fairly extensive, predominantly small-scale roofing slate mining operation. Slate is still mined in Altlay today.
