A conservation and study team replaces the maple crosspieces of the Mona Lisa with sycamore ones, and an additional metal crosspiece is added for scientific measurement of the panel's warp.
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.
