Yes, there are the billy goats and the international expos, but St. Martin's croissants (rogale świętomarcińskie) might be Poznań's best-loved trademark. Baked specifically for St. Martin's Day (November 11th), these goodies stuffed with white poppy seeds enjoy fame all around Poland, and it's surprising that a museum dedicated to them has only just recently popped up in Poz. The Croissant Museum hosts numerous daily and weekly shows, one of which is in English and takes place at 14:00 on the weekends and irregularly during the week (check the website for an up-to-date schedule). The 50-minute session includes a multimedia presentation, legends, a tour of the historic museum building, a chance to bake croissants using traditional tools!
