Katowice is the capital and largest city of Silesian Voivodeship, Poland. Located in the middle of the province on the banks of the river Rawa, Katowice's historical importance as Poland's main industrial centre has been indisputable for decades. Once synonymous as a crushingly gray industrial city, contemporary Katowice has expanded to become a vibrant cultural and business center, with the Silesian Philharmonic, the Silesian Museum, and its famous flying saucer-shaped concert hall, the Spodek, calling the city home. Intrepid visitors will find an interesting city with charming secessionist architecture from the early 1900s, historic reminders of the German and communist past, stunning modern architecture, hospitable and proud local people, and easy access to the Beskid Mountains and other neighboring communities. One of the hidden gems of Poland, Katowice especially delights the senses in April with its numerous flowering lilac trees.
