In the shadow of the cathedral Ostrów Tumski, far from the hubbub of the city, is the terra sancta of Wrocław. To get there, you need to cross Tumski Bridge, once the border of church jurisdiction. Representatives of the lay authorities, including princes, were obliged to take off their hats when they crossed the bridge. This is an area of monumental churches, a marvelous Gothic cathedral, the houses of the canons and the archbishop’s palace. The terrace on the cathedral’s northern tower mentioned above offers a great view of the church towers and the Oder River winding through the city. When the gas lamps are lit at night and the most striking architectural landmarks are illuminated, Ostrów Tumski is a breathtaking sight. Those who enjoy Modernism will be intrigued by the Ludowa Hall, which at its opening in 1913 was the largest reinforced-concrete structure in the world. Today it is a venue for trade fairs, exhibitions, concerts and sports events first and foremost matches played by Poland’s best basketball club team, Śląsk Wrocław, a 16-time Polish champion. Wrocaw is a city where culture plays a special role. Important events include the Wratislavia Cantans Music and Fine Arts festival, featuring oratorio and cantata music, the International Festival of Viennese Music and the Wrocław Organ Summer. The city has an opera house, an operetta, numerous theaters and museums, among which the most important is the rotunda housing the Racławice Panorama, a monumental work by Wojciech Kossak and Jan Styka, portraying the victory of insurgents led by Tadeusz Kościuszko over Russian forces at the Battle of Racławice.
