Built as a Gesellschaftshaus ( social functions building ) for the Leipzig Zoological Garden in 1900, this neo-romanesque structure with its tower was, after the war damage had been repaired, put to new use in 1946 as Leipzig’s Congress Hall. But neglect and years of being left empty did great damage to this stately building. From 2010 onward, it was thoroughly renovated, completely refurbished with new, modern technology, and expanded to include new halls. The magnificently restored Congress Center was finally inaugurated in 2015. This book focuses on the rich history of the building and reports on the extensive renovation work and the careful restoration of its wonderful halls, including the unique Art Deco White Hall, by architects HPP Hentrich-Petschnigg & Partners. It also profiles the modern halls and the new components that add to the ensemble’s functionality, and make it a full-fledged convention center-one of the few in Europe with a historic ambience. With elaborately revised plans that illustrate existing (black) and new work (red) in detail.
