Castile is a gorgeous stone, always in our top 5 best-sellers, and is now offered in a fabulous outside courtyard cobble. These cobblestones are 30mm thick (3cm) and come in 10cm x 10cm, 15cm x 15cm and 10cm or 15cm wide by mixed lengths - all sizes are finished with a gently aged edge and textured surface. Choose from the traditional 4inch & 6inch square cobbles, or the mixed length option which is certainly much in demand.
