Charlottenburg is an affluent locality of Berlin within the borough of Charlottenburg-Wilmersdorf. Charlottenburg is located in Berlin’s inner city, west of the Großer Tiergarten park. Its historic core, the former village green of Alt Lietzow, is situated on the southern shore of the Spree River running through the Berlin glacial valley. The Straße des 17. Juni road, former Charlottenburger Chaussee, which runs eastwards from Charlottenburg Gate through the Tiergarten park to Brandenburg Gate, connects Charlottenburg with the historic center of Berlin-Mitte.
In the north and west, the Berlin Ringbahn and the Bundesautobahn 100 (Stadtring) mark the border with the Charlottenburg-Nord and Westend suburbs. Adjacent in the south is the territory of Wilmersdorf. Charlottenburg also borders on the district of Halensee in the southwest, as well as on Moabit, Hansaviertel, and Tiergarten (all part of the Mitte borough) in the east and on Schöneberg in the southeast.
