The Mona Lisa was moved to the Louvre’s Salle des États in 2005.
The move followed a renovation of the room, which is in the Denon wing and is one of the Louvre’s largest exhibition spaces. The painting had been transferred to the Salle Rosa during the renovation, from 2001 to 2005, before returning to the Salle des États.
The 2005 installation was designed around the painting’s conservation and enormous visitor demand. It placed the portrait in a specially engineered case with controlled temperature and humidity, helping protect Leonardo’s fragile poplar-wood panel. The Salle des États also provides space for crowds and allows visitors to view Paolo Veronese’s enormous The Wedding Feast at Cana opposite it.
A common mix-up is the Grande Galerie: the Mona Lisa was displayed there from 1992 to 1995, but that was an earlier temporary relocation. It has also moved for overseas exhibitions and later Louvre renovations, including a temporary transfer in 2019.
