Poland is an eastern European country on the Baltic Sea known for its medieval architecture, Jewish heritage and hearty cuisine. In the city of Krakow, 14th-century Wawel Castle rises above the medieval Old Town, home to Cloth Hall, a Renaissance trading post in Rynek Glówny (market square). Nearby is the Auschwitz-Birkenau concentration camp memorial, and Wieliczka Salt Mine, with tunnels to explore.
