Caption: Purbeck Stone Quarry or Quarr, Swanage, looking north-north-east, Dorset.
Description: The Purbeck Marble quarried in the Isle of Purbeck is not a true marble (metamorphic limestone) but a hard sedimentary limestone containing numerous freshwater gastropod fossils (Viviparus sp.). When polished the numerous fossils give a marble-like finish. The Purbeck limestones were also an important source of roofing materials. The thinly bedded limestones could be split into thin layers which could be used as a roofing slate. The masons' sheds where the stones were dressed surrounding the quarr are all roofed with Purbeck limestone stone slates. Historically, the Isle of Purbeck in Dorset is an important area for the quarrying of building limestone. The local houses are commonly constructed of Purbeck or Portland Stone. The area is also the source of the famous Purbeck Marble, a dark fossiliferous limestone used decoratively in many historic churches and cathedrals in southern England.
