Catcastle Grey
Course grained brown/grey/variegated sandstone.
Good paving material and suitable for severe exposure areas such as sea walls and reservoirs
Quarried at Lartington nr Barnard Castle in Teesdale, this quarry was initially opened up when the railway was laid over Deepdale valley on its route to Carlisle. Consequently the stone was used on many railway bridges North of York as well as the Abutments to Lendal bridge in York. Catcastle’s durable nature also lead to its use on reservoirs and harbour walls in the North East.
Catcastle is a unique stone; its has a coarse grain with occasional large quartz inclusions, and variegated
brown feature markings.
Recently it was used to build Glasgow Sherrifs Court, and Hull Crown Court and the considerable development of the Buchannan Shopping Centre Glasgow. It was also used for the restoration of Stirling Castle, notably the reconstruction of the Great Hall including the full parapet.
