Charlottenburg is an area in Berlin, formerly a borough, now part of Charlottenburg-Wilmersdorf.

It is known for the Schloss Charlottenburg , the largest palace in Berlin.

Elector Frederick III had a summer residence built for his wife Sophie Charlotte by the architect Johann Arnold Nering between 1695 and 1699. After Frederick became the first Prussian King in 1701, the Palace was extended into a stately building with a cours d'honneur. This work was supervised by the Swedish master builder Johann Friedrich Eosander. The eastern New Wing was built by Georg Wenzeslaus von Knobelsdorff between 1740 and 1747 as Frederick the Great's residence.
