Charlemagne Building (City of Brussels)

 directorate, European Union institution

The Charlemagne building 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 building has 3 wings and 15 floors. It is located at 170 Rue de la Loi/Wetstraat, in the City of Brussels, one of the 19 municipalities forming the Brussels-Capital Region. The postal code for the municipality is 1000, but the postal code for the European Commission is 1049.

The building was designed by Jacques Cuisinier and constructed in 1967 at the same time as the Berlaymont Building to group together more scattered departments of the European Commission. However, with the Commission refusing to share the Berlaymont with the Council of the European Union, Charlemagne was given to the Council's secretariat in 1971. This had previously been located in the city centre.
