Limestone is a sedimentary rock type formed by the accretion of skeletal fragments of marine organisms such as coral and shell.

The UK has a wealth of limestone and is sourced mainly from the southern half of the British Isles, however, there are also quarries in Lincolnshire, North Yorkshire and Cumbria. To compliment the UK limestone portfolio, imported stone is commonly sourced from countries such as Portugal, Germany and France.

Limestone is very common in architecture. Cathedrals, churches and numerous public and private buildings provide excellent examples of the durability and beauty of limestone, which in turn forms part of our heritage. It has also been widely used as a landscape and building material since before Roman times. Limestone produces a variety of products such as paving, walling and masonry, also fine carved and moulded work.

The colours of limestones range from white and honey tones to much darker tones such as grey/blue and darker browns. There are a variety of textures from fine even grained stones to extreme coarse open textured such as Portland roach bed.
