Limestone is a sedimentary rock composed largely of the mineral calcite (calcium carbonate: CaCO3). The primary source of the calcite in limestone is most commonly marine organisms. These organisms secrete shells that settle out of the water column and are deposited on ocean floors. Pure limestones are white or almost white. Because of impurities, such as clay, sand, organic remains, iron oxide and other materials, many limestones exhibit different colors, especially on weathered surfaces.
Limestone is especially popular in architecture, and many landmarks around the world, especially in North America and Europe, are made primarily of the material. So many buildings in Kingston, Ontario, Canada were constructed from it, that it was nicknamed the 'Limestone City'. Many medieval churches and castles in Europe are made of limestone. Beer stone was a popular kind of limestone for medieval buildings in southern England. Limestone is readily available and relatively easy to cut into blocks or more elaborate carving. It is also long-lasting and stands up well to exposure.
Light in tone and subtle in colour, Limestone creates fresh, light surfaces which complement natural wood and clean modern interiors. Limestone is a highly versatile stone in interior design being used to highlight rustic detail or as part of a minimalist design. Its versatility in application is due to its different finishes, being attractive both in clean, unpolished beige stone and highly polished, smooth cream surfaces.
