Renovation of the Centennial Hall

The Centennial Hall was designed as a monumental building entirely of reinforced concrete. Soon it became a model for modernist buildings of that era. During the years 2009-2011, the biggest renovation since its completion took place. All activities described in the following paper aimed to put the Centennial Hall into good repair and adjust it to the applicable requirements of modern public buildings. The primary aim is to preserve the authenticity of the original materials used in construction through the use of remedial technologies, thereby maintaining the historical integrity of the building. The Centennial Hall was built in 1911-1913 according to the design by Max Berg. The building is located in the central part of the old Exhibition Grounds, currently called the Centennial Hall Complex. The complex is situated in the immediate vicinity of Szczytnicki Park and the Zoological Gardens, in the north-east part of Wroclaw. The ribbed dome of the Centennial Hall was the biggest in the world at the time of the building's completion. It exceeded the size of the dome of Hagia Sofia and the Pantheon in Rome. The unprecedented span of the dome constituted a challenge for designers who had to use precursor construction solutions. Since its completion, the Centennial Hall has been a model for monumental modernist buildings and one of the most significant works of the 20th century architecture. The Centennial Hall (the People's Hall) was entered to the register of monuments of the city of Wroclaw in 1962, and in 1977, it was re-entered under the name of the People's Hall Complex (i.e., Centennial Hall, Four-Dome Pavilion, Restaurant Pavilion, Pergola, the
