The modernist district is centered around the monumental Silesian Parliament building (1923-1929), which architecture is mostly functionalist but still will neoclassical references on the facades. During World War II, the building became headquarters of the Reichsgau Oberschlesien and part of the interior was redesigned by Albert Speer, Hitler's favorite architect, to resemble the interior of the Reich Chancellery. The nearby Cathedral of Christ the King (1927-1955, with dome lowered by 34 meters compared to original design) is also neoclassical but with an ascetic interior (including a tabernacle and a golden mosaic funded by future pope, Joseph Ratzinger). Other buildings, designed in mid-to-late 1920s and 1930s, are mostly modernist or functionalist. A symbol of the city in the interwar period, Drapacz Chmur (literally: "The Skyscraper"), was the first skyscraper built in Poland after World War I, and the first building in the country to be based on a steel frame.
