This annual event encourages locals and tourists alike to visit Kraków's many museums and galleries, which for this special Sunday in November will not only make their permanent and temporary exhibits available to the public, but also prepare special attractions like workshops, tours and talks. Over 50 places will be participating, including Wawel, and cultural institutions in Wieliczka and Niepołomice. Most museums will be open during their regular hours, and while admission to most will be reduced to only 5zł, some will even be free of charge. Check each institutions website for details of the day's programme, and note that some events require online reservations.
