Michelangelo's 'The Last Judgment' fresco undergoes 3-month cleaning at Sistine Chapel

Michelangelo’s “The Last Judgment,” the imposing fresco of heaven and hell which dominates the Sistine Chapel, is undergoing its first major restoration in three decades, the Vatican said Monday. The Sistine Chapel will remain open to visitors during the three-month cleaning, albeit with scaffolding partially obstructing the view of the fresco, the Vatican Museums said in a statement. The cleaning, the first major restoration since 1994, will remove microparticle buildup on the plaster from so many people visiting each day.
