Pisa’s leaning tower may have all the fame, but Krakow’s Town Hall Tower (Wieża Ratuszowa w Krakowie) is a must-see nonetheless. Quite literally – as one of the focal points of Krakow’s main market square, it’s pretty hard to miss. Built towards the end of the 13th century, the 70-meter tall tower started leaning (it currently tilts by as much as 55 centimeters) after massively strong winds in 1703. It should be said, however, that the tower survived many fires and was therefore weakened considerably throughout the years.To this day, the tower is the only remaining part of Krakow’s old town all. Visitors interested in visiting the tower should not worry; the tower is perfectly safe for visitors and even has an observation deck on its upper floor, reachable by a narrow staircase. The tower, as part of the Historical Museum of Kraków and because of its location in the old Cloth Hall, often has artworks and medieval costumes on display. There’s also an underground café, which is housed in the former city dungeons and torture rooms.
