also known as Purbeck Marble, Purbeck Stone, Dorset Black Limestone
Known since medieval times as "Purbeck Marble" (though technically a limestone), this dense grey-to-black stone from the Isle of Purbeck was the prestige interior stone of English Gothic architecture. The columns at Salisbury Cathedral, Canterbury Cathedral, and Westminster Abbey are Purbeck Limestone. On polishing, it reveals distinctive freshwater gastropod and bivalve fossils embedded in a dark matrix, producing a richly textured surface unlike any other English stone.

Medieval English craftsmen used the term "marble" for any dense limestone that could be polished to a shine. Purbeck Limestone takes an excellent polish and its fossil-rich texture was valued like genuine marble. The name has persisted for over 800 years.
The slender dark polished columns in Salisbury Cathedral, Canterbury Cathedral choir, and Westminster Abbey chapter house are Purbeck Limestone. It was the defining decorative interior material of 13th-century English Gothic.
