Watch on 123Movies. The Nikolaikirche is the oldest building in Berlin. The reconstruction of this building in 1981 marked the beginning of the reconstruction of the historic heart of Berlin. The film shows the work on the Nikolaikirche, the Ephraim-Palais and the equestrian statue of St. George and describes how the restoration was carried out in painstaking detail, using almost forgotten craftsmanship. In 1987, the reconstructed quarter with its mixture of old and new was handed over to the people of Berlin.
