Purbeck stone is a type of limestone found in the Isle of Purbeck in Dorset, England. It is known for its durability and unique colors, ranging from light grey to dark blue. This stone has been used for centuries in construction and sculpture, making it a popular choice for both historical and modern buildings. The extraction of Purbeck stone dates back to Roman times, and it has been used in notable structures such as Westminster Abbey and St. Paul's Cathedral. Its fine grain and ability to take a polish make it ideal for decorative elements, including flooring and monuments.
