Charlemagne building

The Charlemagne structure, completed in 1967, is a high-rise in the European Quarter of Brussels, which houses the Directorate-General for Economic and Financial Affairs, the Directorate-General for Trade and, since 2015, the Internal Audit Service of the Commission. The structure has 3 wings and 15 floors. The Council moved out to the Justus Lipsius structure in 1995 allowing it to be refurbished. The renovation was completed in 1998 by Helmut Jahn, replacing the largely concrete exterior with a glass one.
