The Mona Lisa is moved to a new location within the Louvre's Salle des États. It is displayed in a purpose-built, climate-controlled enclosure behind bulletproof glass. The humidity is maintained at 50% ±10%, and the temperature is maintained between 18 and 21 °C. To compensate for fluctuations in relative humidity, the case is supplemented with a bed of silica gel treated to provide 55% relative humidity. The painting is now illuminated by an LED lamp.
