Berlin was devastated by air raids, fires, and street battles during the Second World War, and many of the buildings that had survived in both East and West were demolished during the postwar period. Much of this demolition was initiated by municipal architecture programs to build new business or residential districts and the main arteries. Much ornamentation on prewar buildings was destroyed following modernist dogmas, and in both postwar systems, as well as in the reunified Berlin, many important heritage structures have been reconstructed, including the ''Forum Fridericianum'' along with, the State Opera (1955), Charlottenburg Palace (1957), the monumental buildings on Gendarmenmarkt (1980s), Kommandantur (2003) and also the project to reconstruct the baroque façades of the City Palace. Many new buildings have been inspired by their historical predecessors or the general classical style of Berlin, such as Hotel Adlon.
