The Western Allies (the USA, Britain and France) never formally acknowledged the authority of the East German government to govern East Berlin; the official Allied protocol recognized only the authority of the Soviet Union in East Berlin in accordance with the occupation status of Berlin as a whole. The United States Command Berlin, for example, published detailed instructions for U.S. military and civilian personnel wishing to visit East Berlin. In fact, the three Western commandants regularly protested the presence of the East German National People's Army (NVA) in East Berlin, particularly on the occasion of military parades. Nevertheless, the three Western Allies eventually established embassies in East Berlin in the 1970s, although they never recognized it as the capital of East Germany. Treaties instead used terms such as "seat of government."
On 3 October 1990, West and East Germany were reunited, thus formally ending the existence of East Berlin.
Since reunification, the German government has spent vast amounts of money on reintegrating the two halves of the city and bringing services and infrastructure in the former East Berlin up to the standard established in West Berlin. Despite this, there are still obvious differences between eastern and western Berlin. Eastern Berlin has a distinctly different visual aspect, partly because of the greater survival of prewar façades and streetscapes, some still showing signs of wartime damage, and partly because of the distinctive style of urban Stalinist architecture used in the GDR. As in other former East German cities, a small number of GDR-era names commemorating socialist heroes have been preserved, such as Karl-Marx-Allee, Rosa-Luxemburg-Platz and Karl-Liebknecht-Straße; this followed a long process of review in which many such street names were deemed inappropriate and were changed. Still visible throughout former East Berlin are the characteristic "Ampelmännchen" on some pedestrian traffic lights. These days they are also visible in parts of the former West Berlin following a civic debate about whether the "Ampelmännchen" should be abolished or disseminated more widely.
