During World War II, the Allied bombing campaign and fierce fighting in the Battle of Berlin caused severe damage; the roof was almost completely destroyed as were the statues above the rear entrance, and there was substantial water damage. In the first phase of reconstruction in 1951, the statue of the goddess of Fortuna was removed, and is assumed to have been smelted in 1962. The remaining statues, urns, and other carvings on the exterior were removed in 1976–77 due to rain damage. It was completely refurbished in the 1990s and exterior restoration required replacement of some 180 sculptural elements, including the allegorical figures of the virtues, giant vases, window embrasures and one of the columns. The original mansard roof was reconstructed in 1998–99.
