The Centennial Hall is a historic building in Wrocław, Poland. It was designed by Max Berg in 1911, when the city was known as Breslau and belonged to the Province of Silesia in the German Empire, to host a 1913 exhibition celebrating the centennial of the Battle of Leipzig. The building is one of the most important examples of early modernist and expressionist architecture. In 2006, it was inscribed on the list of UNESCO World Heritage Sites in Poland. The Wrocław exhibition ground, surrounding the hall, also includes a pergola, the needle-like monument Iglica, and the Four Domes Pavilion, which is part of the National Museum.Photograph credit: Jarek Ciuruś
