Why Krakow for a city break?
Krakow is one of Europe's most complete medieval cities — a city that escaped World War II almost entirely intact, preserving a UNESCO World Heritage old town of Gothic churches, Renaissance merchants' houses, and the Wawel castle and cathedral on their limestone hill above the Vistula. The Cloth Hall in the main square is still a functioning market, as it has been since the 13th century. The Kazimierz Jewish quarter — site of one of Europe's most important Jewish communities before the Holocaust — has been sensitively transformed into the city's most interesting neighbourhood.
From most UK airports it's a direct two-and-a-half-hour flight, and Krakow remains one of the most affordable city breaks in Europe — a three-course dinner with excellent Polish vodka costs under £20, good hotels are well under £100, and most of the best things to do cost very little. Auschwitz-Birkenau, 75km west, is an essential but profoundly demanding day trip. The Wieliczka Salt Mine, an extraordinary underground city of carved salt, is 15km southeast. Both deserve at least half a day.
