Charlottenburg is an affluent locality of Berlin within the borough of Charlottenburg-Wilmersdorf. Established as a town in 1705 and named after late Sophia Charlotte of Hanover, Queen consort of Prussia, it is best known for Charlottenburg Palace, the largest surviving royal palace in Berlin, and the adjacent museums.
Charlottenburg was an independent city to the west of Berlin until 1920 when it was incorporated into "Groß-Berlin" (Greater Berlin) and transformed into a borough. In the course of Berlin's 2001 administrative reform it was merged with the former borough of Wilmersdorf becoming a part of a new borough called Charlottenburg-Wilmersdorf. Later, in 2004, the new borough's districts were rearranged, dividing the former borough of Charlottenburg into the localities of Charlottenburg proper, Westend and Charlottenburg-Nord.
