Berlin is the capital of the Federal Republic of Germany and is the seat of the President of Germany, whose official residence is Schloss Bellevue. Since German reunification on 3 October 1990, it has been one of the three city states, together with Hamburg and Bremen, among the present sixteen states of Germany. The Bundesrat ("federal council") is the representation of the Federal States (Bundesländer) of Germany and has its seat at the former Prussian Herrenhaus (House of Lords). Though most of the ministries are seated in Berlin, some of them, as well as some minor departments, are seated in Bonn, the former capital of West Germany. The European Union invests in several projects within the city of Berlin. Infrastructure, education and social programs are co-financed with budgets taken from EU cohesion funds.
