You may not always get a princely welcome, but the museum itself ranks amongst the finest private museums in Europe. Initially founded as a patriotic endeavour during the era of Poland's collapse, the museum has had a dramatic history. It's a wonder that so much of the collection has survived at all. But survive it has, and here you can take a spirited journey through Poland's history, with a host of eccentric extras on the way. You may get sick of hearing about the Leonardo da Vinci, and the nineteenth century rooms are often inexplicably closed, but all things considered, this is an unmissable element in Cracow's cultural canon.
