Due to Berlin's history of division during the Cold War, the city contains central business districts both in West (Kurfürstendamm) and East Berlin (Alexanderplatz), as well as a newly built business district near the Potsdamer Platz. The city's historic center – home to the Reichstag building, as well as the Brandenburg gate and most federal ministries – was largely abandoned when the Berlin Wall cut through the area. Only after the reunification with the redevelopment of Potsdamer Platz, and the construction of numerous shopping centers, government ministries, embassies, office buildings and entertainment venues, was the area revived.
