Katowice city center has an axis design, along the main railway line, developed by an industrialist Friedrich Grundman in mid-19th century. Most of the city center in Katowice developed in late 19th and early 20th century, when it was part of the Kingdom of Prussia and had a German-speaking majority. As a result, architectural styles of that era are similar to those in other Prussian cities such as Berlin or Wrocław (then Breslau); primarily renaissance revival and baroque revival, with some buildings in gothic revival, romanesque revival, and art nouveau styles.
