During the Middle Ages, Krakow was one of the most important trading stops along the caravan routes that supplied Europe. Pretty much everything and anything that was sold on the continent came through the city, and so, when archeologists started digging in Krakow's main square (a marketplace for over 1000 years), they found treasures from across the globe, many of which no longer can be found in their places of origin. This underground museum was built on the original dig site and it's easily the best attraction to open in Krakow for a long time. It offers an interactive and imaginative recreation of life in the medieval city and later,, along with displaying actual finds from the long-term archaeological digs here. Wall text is in Polish and English. There are often long waits to get in, but don't let that deter you: this is truly one of the most engaging history museums in Europe.
