Portland stone is a limestone from the Tithonian stage of the Jurassic period quarried on the Isle of Portland, Dorset. The quarries consist of beds of white-grey limestone separated by chert beds. It has been used extensively as a building stone throughout the British Isles, notably in major public buildings in London such as St Paul's Cathedral and Buckingham Palace. It is also exported to many countries—Portland stone is used in the United Nations headquarters building in New York City, for example.
The term "Portland Cement" was coined by Joseph Aspdin who in 1824 patented a hydraulic binder created by burning a mixture of limestone and clay, resembling the previously existing Roman cement and presenting a texture very close to that of the oolitic Portland stone.
