Materials in Focus: Portland Stone

From ancient Jurassic sea floors to the modern skylines of London: Great British Stone.

Portland stone is a type of limestone that dates back to the Tithonian age of the Late Jurassic, quarried on the Isle of Portland in Dorset and worked by craftsmen and artisans since Roman times.

It has been used in sculpture and architecture for centuries for its durability, versatility and signature creamy white colouring. Portland stone is present across the UK in a myriad of iconic buildings, including St Paul’s Cathedral, Buckingham Palace and the National Gallery.

In Alice Cunningham’s work Reach, the block of Portland stone contained fossilised oyster shells, as the stone develops in a marine environment. In carving the stone, Alice revealed the sells inside, which create a striking abstract blue pattern on the work’s surface.

For UK clients, Portland stone is also a considered sustainable choice — lower embodied carbon than imported alternatives, and rooted in a quarrying tradition that connects your commission not just to British architectural history, but to the land itself.
