King Barrow Quarry is a disused site of former 19th century stone quarries on the Isle of Portland, Dorset, England. It is located in the north-east corner of Tophill. The quarry, now a Dorset Wildlife Trust nature reserve, covers 12.2 hectares.[1] Both King Barrow and the nearby Tout Quarry make up the Dorset Wildlife Trust's Portland Quarries Nature Park. Portland also has two butterfly reserves: Broadcroft Quarry and Perryfield Quarry.
