Today I got a nice postcard from Poland! The postcard shows an aerial view of the Main Market Square in Kraków. The square is located at the center of the city and is considered to be the largest medieval town square in Europe. In the middle of the square we see Cloth Hall. The square typically bustles with life and currently sits atop the biggest underground museum in the world. The site is part of Old Town Kraków, a UNESCO World Heritage Site. Beautiful stamps were used! Thanks Jolanta!
