Plan your route


Travel by Plane

Berlin airports: Tegel Airport in the northwest of Berlin and Schönefeld Airport on the southern outskirts. S-Bahn trains, as well as regional trains, leave the Schönefeld Airport directly for the center of Berlin. From Tegel Airport the city center is easy to reach with the TXL Express bus.

Travel by Car

From any direction, all highways and national roads lead to the capital city Berlin. They all cross the highway which encircles Berlin, known as the “Berliner Ring.” From there urban highways and exits – marked with the word “Stadtmitte” or “Zentrum” – guide drivers towards the center of Berlin. Car and bus parking available in front of the building.

Travel by Train

Travelers arriving in Berlin by train arrive at one of Berlin’s main train stations. Almost all trains stop at the Central Sation (Hauptbahnhof) as well. All railway stations have direct links to public transportation (taxi and subways).
