Krakow is beautiful, a jewel among European cities. People have been living and building here since the 9th century. The Old Town historical district in Krakow’s heart is actually the medieval city established in 1257. Krakow remains the undisputed architectural capital of Poland and home to one of Europe’s oldest universities. The many parks and the Planty, the green city belt surrounding the city centre, make Krakow, a wonderful city to visit. Krakow’s entire stare miasto, old town, is lovely, every street worth a slow stroll. At its centre is the Rynek Glowny, one of the most beautiful market squares in Europe. The Kosciol Mariacki in its northeast corner, is a richly decorated cathedral, with a 500-year-old carved altarpiece. Diagonally across the square stands the lonely town hall tower spared when the rest of the building was demolished in 1820. Sitting on the Wista River, is the Wawel Castle, the finest surviving piece of Renaissance architecture in Poland. The castle was the royal seat of Poland, and is the city's main tourist attraction. The grounds consist of the palace, a huge Cathedral and a large garden. The Royal Cathedral dominates the complex of Wawel. It was the coronation site and burial place of almost all of monarchs of Poland. Built in the early 11th century in Romanesque style its tower offers a splendid view of Krakow. The beauty of its old architecture, the ambience of great culture, art and literature, the charm of its numerous cafes, bars and pubs, always full of locals and tourists, makes this city one of world's best tourist destinations.
