The Nikolaikirche is the oldest building in Berlin. In 1981, the reconstruction of this building marks the beginning of the reconstruction of the historical core of Berlin. The film shows the work on the Nikolaikirche, the Ephraimpalais 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 rebuilt quarter, with its mixture of old and new, was handed over to the people of Berlin.
