I've made this model after taking over 100 photos of the Hall- 30 of them have been included in model as materials.
The Centennial Hall is a historic building constructed in Wrocław (Breslau) in 1913 when the city was part of the German Empire. It was listed as a UNESCO World Heritage Site in 2006.
The hall was built in the German Empire in 1911–1913 according to the plans of Max Berg, during preparations for an exhibition commemorating the 100th anniversary of the Battle of the Nations, as it is also called, reminding that most of Europe was involved.
The cupola was made of reinforced concrete and with an inner diameter of 69 m and 42 m high; it was the largest building of its kind at the time of construction. The symmetrical quatrefoil shape with a large circular central space seats 6,000 persons. The dome is 23m high, made of in steel and glass. The Jahrhunderthalle , a name also chosen for halls in Bochum (1902) and Frankfurt (1963) for different anniversaries, had been intended to commemorate a 19th century event, but instead became a key reference for the development of reinforced concrete structures in the a 20th century.
