Wandering through the streets of Krakow is like stepping into a European history book. There are carefully preserved medieval buildings around almost every corner; the city's many churches are rich with baroque and Renaissance influences; and haunting wartime memories mingle with nostalgia for the years of communist rule. Nevertheless, Krakow is a modern city. A predominantly young population can be found frequenting the many popular bars and restaurants, and several world-class museums have opened in recent years using cutting-edge technology specially geared to international visitors.
