Founder of Poland’s first-ever museum, Princess Izabela Czartoryska was an art collector of the late 1700s and early 1800s. Becoming a princess by dint of her marriage to Prince Adam Kazimierz Czartoryski in 1761, the former Countess Fleming was influenced by her sojourn in Paris a decade later. There she met Voltaire, Benjamin Franklin, and Jean-Jacques Rousseau, returning to Poland to convert the Czartoryski Palace into a center for intellectual debate and discussion. Following its destruction during the Uprising against Russia, she had it rebuilt and filled with rare treasures. It was her grandson, Wƚadysƚaw, who had it converted in 1878 into the Czartoryski Museum we know today. One of Krakow’s most remarkable museums, it contains Da Vinci’s Lady with an Ermine, Spanish, Venetian, and Flemish pieces, as well as some personal artifacts of Napoleon, Captain Cook, and Frederick the Great. 
The museum is currently closed for renovation and set to re-open in 2015.
