Where is the European Union headquartered?

The offices of the European Commission are based in Brussels, Belgium, and the European Parliament has chambers both in Brussels and Strasbourg, France. There is no official capital of the European Union, but most day-to-day operations take place in Brussels.

The European Commission oversees most day-to-day European Union business from its offices in Brussels. Although the European Parliament maintains two chambers, the facilities in Brussels see more use due to the proximity to the European Commission. The European Union also maintains a headquarters for U.S. relations in Washington, D.C., functioning as a de facto embassy for the European Union in the United States.
