Penmaenmawr & Welsh Granite Co.

Owned and operated the granite quarry on the headland between Conwy and Llanfairfechan from the 1830s to the 1960s, working it for setts and later roadstone. Its granite was lowered by self-acting inclines to a three-foot gauge tramway serving jetties on the shore, and from 1848 sent out mainly by the Chester to Holyhead railway; the internal railway lasted until trucks replaced it in the 1960s.
