The Espace Léopold (French, commonly used in English) or Leopoldruimte (Dutch) is the complex of parliament buildings in Brussels (Belgium) housing the European Parliament, a legislative chamber of the European Union (EU).
It consists of a number of buildings, primarily the oldest, the Paul-Henri Spaak building, which houses the debating chamber and the President's offices, and the Altiero Spinelli building which is the largest. The buildings are located in the European quarter in the east of Brussels, with building starting in 1989.
The complex is not the official seat of Parliament, which is the Immeuble Louise Weiss in Strasbourg, France, but as most of the other institutions of the European Union are in Brussels, Parliament built the Brussels complex in order to be closer to their activities. A majority of the Parliament's work is now geared to its Brussels site, but it is legally bound to keep Strasbourg as its official home.
Parliament, its committees and plenary meetings are open to the public. Free audio guided tours are offered when parliament is not holding a plenary meeting. The buildings, containing several shops and banks, are largely open to the public and receive 15,000 people a day. The old station building houses the Belgian public information office on the European Parliament, and "infodoc", a specialised literary resource on the Parliament for academics and journalists. A more general public information resource is available at the "infopoint" on the esplanade side of the Spinelli building.
