The Kirkby quarry is located on Kirkby Moor, just above the village of Kirkby-in-Furness and has been operated for well over 400 years. Kirkby Stone is an even blue grey colour throughout. Kirkby Stone has been used for generations to provide walling, flooring, roof coverings, cills and copings. Architects and designers around the world have long taken advantage of its natural beauty, durability and adaptability to create classic weather resistant details and surface finishes. Kirkby Stone is sedimentary in nature and was formed in the Silurian period, some 300-350 million years ago.
