Valentia Slate Company Ltd

Valentia Slate Company Limited is Ireland’s longest‑running quarry, operating continuously since 1816 on the rugged western edge of Kerry. As the most westerly quarry in Europe, the family‑run business extracts the distinctive, non‑porous Valentia Slate and transforms it in‑house into a range of high‑quality, low‑carbon products.

Specialising in durable roofing and flooring slates, finely crafted gravestones, and bespoke architectural elements such as panels, exterior seating, bathroom fittings and building stone, Valentia Slate blends a 200‑year heritage with contemporary design principles. The company’s zero‑waste philosophy and use of low‑impact manufacturing techniques ensure that each piece retains the natural beauty and strength of the raw material while contributing minimal embodied carbon.

Valentia Slate’s work can be found in historic landmarks—from the Houses of Parliament and Westminster Abbey to the Paris Opera House—and continues to serve architects, designers and heritage projects seeking a unique, locally sourced stone with an unrivalled terroir.
