Situated on the Vistula River in Lesser Poland Voivodeship, the city has a population of 804,237 (2023), with approximately 8 million additional people living within a 100 km (62 mi) radius.[9] Kraków was the official capital of Poland until 1596,[10] and has traditionally been one of the leading centres of Polish academic, cultural, and artistic life. Cited as one of Europe's most beautiful cities,[11] its Old Town was declared a UNESCO World Heritage Site in 1978, one of the world's first sites granted the status. The city began as a hamlet on Wawel Hill and was a busy trading centre of Central Europe in 985.[12] In 1038, it became the seat of Polish monarchs from the Piast dynasty, and subsequently served as the centre of administration under Jagiellonian kings and of the Polish–Lithuanian Commonwealth until the late 16th century, when Sigismund III transferred his royal court to Warsaw. With the emergence of the Second Polish Republic in 1918, Kraków reaffirmed its role as the nucleus of a national spirit. After the invasion of Poland, at the start of World War II, the newly defined Distrikt Krakau became the seat of Nazi Germany's General Government. The Jewish population was forced into the Kraków Ghetto, a walled zone from where they were sent to Nazi extermination camps such as the nearby Auschwitz, and Nazi concentration camps like Płaszów.[13] However, the city was spared from destruction. In 1978, Karol Wojtyła, archbishop of Kraków, was elevated to the papacy as Pope John Paul, the first non-Italian pope in 455 years.[14]
