The icon has been put back in the Trinity Cathedral at the Trinity-Sergius Lavra after work on its climate-controlled display case was completed.
The Tretyakov Gallery said the icon was returned on October 6. Museum staff attended the installation and will continue monitoring the display case, which maintains the conditions required for its preservation. A copy of Rublev’s Trinity was kept in the cathedral while the case was being repaired and inspected.
The icon was removed from the iconostasis in mid-September and moved to the Lavra’s workshops so adjustments could be made to the climate capsule. The Moscow Patriarchate said the day before that the icon’s condition was being checked as part of a scheduled inspection.
Andrei Rublev painted the icon in the 15th century for the cathedral. After 1917, it passed through Soviet restoration workshops and was briefly displayed in a museum in Sergiev Posad before entering the Tretyakov Gallery in 1929. The Russian Orthodox Church requested its transfer to the Lavra in 2023. It was moved to Sergiev Posad in early 2024.
