LONDON - MAY 06:  Stone restorer Nicholas Hague measures a roundel on Westminster Abbey's Cosmati Pavement on May 6, 2008 in London, England. Centuries of dirt and grime will be painstakingly removed from this work of medieval craftsmanship during a 535,000 GBP restoration project. The 56 sq/m intricate mosaic floor lies in front of theHigh Altar. Long hidden under rolls of carpet,  it is made from small inlaid pieces of semi-precious stone, marble, glass and metal set in squares and circles some of which is thought to have been recycled from the ruins of ancient Rome. Commissioned by Henry III to be a centrepiece of the re-built 13th century Abbey. Getty Images logo Getty Images 21 months ago
