Da Vinci's 'Last Supper' Battles Indoor Pollution

摘要

Having survived for hundreds of years through political upheaval-including bombings during World War II-Leonardo da Vinci's masterpiece "The Last Supper" now faces the risk of damage in its location in one of Western Europe's most polluted cities. In late 2009, the refectory of Santa Maria delle Grazie Church, where the painting is located, installed a sophisticated heating, ventilation, and air conditioning system to protect the painting from the polluted air of Milan, Italy.
