St Bees is a dark red sandstone of Permo-Triassic age, which forms the sea cliffs of St Bees Head near Whitehaven in Cumbria. From the Birkhams Quarry in Whitehaven, this distinctive close bedded and fine grained sandstone has proved to be a popular choice of building stone for centuries, both in the UK and USA. St Bees was used as ballast on ships to the US and then as a Brownstone substitute for building in the US and Canada.
In the UK St Bees has been used from Scotland to the South of England. Its physical performance results in a stone which is extremely durable and versatile for projects ranging from traditional walling through to large scale specification and restoration.
