Digging deep for Portland Stone

The Island of Portland has literally given its heart to London, and the heart of London comes mainly from Portland. Many of London's most recognizable buildings and monuments are constructed either wholly or partially from the white Upper Jurassic oolite quarried from Portland. St Paul's Cathedral, the British Museum, The Bank of England and more recently the New London Stock Exchange in Paternoster Square and the Bomber Command Memorial and the tube station in Green Park, are all built using Portland Stone. London is not the island's only beneficiary, Portland stone has also been widely used throughout the rest of Great Britain as well as having been exported for use in many other countries.
