In 2016 the collections and Museum building were donated by Prince Adam Karol Czartoryski to the Polish Nation on his behalf and that of his direct ancestors of the Czartoryski Main Branch State Treasury. The Princes Czartoryski Foundation received from the Polish Nation (the Ministry of Culture) $105 million, constituting less than 5% of the 3 billion euros estimated market value of the collections. The agreement also transferred to the Polish State the rights to any future claims to works of art that had been plundered from the collections.
