Portland Stone is a type of limestone that is commonly used in the construction of traditional buildings in the London area.

Limestone is a sedimentary rock formed during four geological eras: Cretaceous, Jurassic, Permian and Carboniferous, spanning 70 – 345 million years ago.

It consists of calcium carbonate, and is formed by the compaction of calcite, primarily from marine organisms, at the bottom of shallow lakes and seas. The presence of marine organisms and other fossil inclusion. Due to the presence of a variety of minerals, limestone presents numerous colours, ranging from light grey Portland Stone, to creamy Bath stone, the brown limestone of Dorset and the dark grey Purbeck stone, also from Dorset. Purbeck can be polished to give a faux marble effect and so came to be known as ‘Purbeck marble’, popular in the 19th century for high quality architectural interior decoration and thin columns.

During the 19th and early 20th centuries limestone, particularly Portland Stone, became popular in the UK for building banks, civic buildings and educational establishments, many of which were in the classical style.
