During the last decade, Krakow’s market square has been heavily excavated to create what is now one of the city’s most intriguing museums. The subterranean Rynek Underground museum takes you directly under the square to explore Krakow’s history as one of the most important commercial and cultural cities of central Europe. This is a very modern twist on an archaeology museum, with highly interactive exhibits throughout the dimly lit passageways that try to recreate life in Krakow during the Middle Ages. Look out especially for the holograms of medieval characters who hurl insults at visitors in their own language as they appear throughout the maze of excavated tunnels.
