Bowers Quarry
United Kingdom
Bowers Quarry/Mine is an active stone quarry on the west side of the Isle of Portland, Dorset, England. The quarry is operated by Albion Stone and became the site of the first Portland stone mine. In October 2002 the firm successfully initiated Portland's first ever underground mining operation, which was a precursor to Jordans Mine, which would start in 2008. It has also been the selected site for the planned Mass Extinction Memorial Observatory.
