In short: Designed by Max Berg and completed in 1913, Wrocław’s Centennial Hall was a marvel of reinforced concrete. While it served as a multifunctional arena for decades, its central dome once featured an Iron Cross pattern that communist authorities felt compelled to shroud during the Cold War era.

Constructed between 1911 and 1913, the Centennial Hall was originally commissioned to commemorate the 100th anniversary of the Battle of Leipzig. Architect Max Berg envisioned a massive, multifunctional space for exhibitions and performances. At the time of its completion, the building’s cupola—with an inner diameter of 69 meters and a height of 42 meters—was the largest reinforced concrete structure of its kind. The design, featuring a symmetrical quatrefoil shape, became a foundational reference for 20th-century engineering.

The hall’s history is deeply intertwined with the shifting political landscape of the region. Originally named Jahrhunderthalle, it was built in the Silesian capital of Breslau. Following World War II and the 1945 Potsdam Agreement, the city became part of Poland, and the hall was renamed Hala Ludowa, or People’s Hall. During the communist era, the structure’s interior lantern, which displayed a distinct Iron Cross pattern, was intentionally hidden from view. This symbol, created by King Frederick William III in 1813, had become a prominent German military honor.

Today, the site is recognized as a UNESCO World Heritage Site and a Polish national Historic Monument. It remains a vibrant hub for sporting events, concerts, and business summits, having undergone extensive renovations in 1997, 2010, and 2009–11. The surrounding grounds, designed by Hans Poelzig, include a concrete pergola and a large pond, maintaining the site’s status as a significant landmark. In 2014, the building received a grant from the Getty Foundation to support its ongoing preservation, ensuring that this early pioneer of modern architecture continues to serve the public.
