Berlin serves as both a city and the capital of the Federal Republic of Germany.
The President of Germany, who primarily holds ceremonial duties as outlined by the German constitution, resides officially in Schloss Bellevue.
As the heart of the German executive branch, Berlin hosts the Chancellery (Bundeskanzleramt), opposite which stands the Bundestag, the German Parliament, located in the refurbished Reichstag building since the governmental shift to Berlin in 1998.
The Bundesrat, functioning similarly to an upper house and representing the Federal States (Bundesländer) of Germany, is situated in the erstwhile Prussian House of Lords.
The capital is also home to the ministries and departments of Defense, Justice and Consumer Protection, Finance, Interior, Foreign Affairs, Economic Affairs and Energy, Labour and Social Affairs, Family Affairs, Senior Citizens, Women and Youth, Environment, Nature Conservation, Building, and Nuclear Safety, Food and Agriculture, Economic Cooperation and Development, Health, Transport, Digital Infrastructure, and Education and Research.
