Because it was raining, we took the opportunity to go to the Rynek Underground museum our last day in Poland. Here, we're looking up at St. Mary's Basilica through the Louvre-Pyramid-like fountain that's above ground in the Kraków town square. Archeologists figured out that there were historical artifacts under the Sukiennice in the center of the city, and in 2005, they began digging up the entire area, only to discover that there was an entire Medieval market preserved in tunnels under the street. When you enter the museum, you're actually in the remains of that market, and you walk on transparent catwalks to look down into the stalls. You can also learn about POLISH VAMPIRE BURIAL, which is reason enough to visit.
