Caption: Easton Quarry, Isle of Portland, Dorset.
Description: There are several quarries in the Easton area working the white freestone limestones known as Portland Stone. In the early 19th century, when many of the quarries were still in the hands of the Crown, they were principally worked by convict labour. Large stone columns are a feature of most classical stone buildings and in later times many British architects copied such classical themes. Portland Stone proved to be ideal for this purpose because the beds of limestone are quite thick. Here a section of stone column is being turned on lathe at the works of the Bath & Portland Stone Company. The section is of 4 ft. diameter, and is one of five constituting a column 25 ft. high. As Portland Stone seems to be less affected by pollution than other United Kingdom limestones it has been widely used in London, particularly since the early 19th century e.g. Custom House, St. Paul's Cathedral, The Bank of England, Whitehall and Downing Street.
