They call it the Poznan Croissant Museum. I’m not sure if a museum is the right word for this place. More like the experience! The St. Martin Croissants are super unique and special. In fact, they are so special that they are protected. Yes, they are legally protected – not only in Poland but in all of the EU. Come with us to the Poznan Croissant Museum, or Rogalowe Muzeum Poznania, as it is called in Poland.
