text: Parliament buildings The European Parliament's buildings are located to the south between Leopold Park and the Place du Luxembourg, over Brussels-Luxembourg Station, which is underground. The complex, known as the "Espace Léopold" (or "Leopoldsruimte" in Dutch), has two main buildings: the Paul-Henri Spaak building and the Altiero Spinelli building, which cover . The complex is not the official seat of the Parliament with its work being split with Strasbourg (its official seat) and Luxembourg (its secretariat). However, the decision-making bodies of the Parliament, along with its committees and some of its plenary sessions, are held in Brussels to the extent that three-quarters of its activity take place in the city. The Parliament buildings were extended with the new D4 and D5 buildings being completed and occupied in 2007 and 2008. It is believed the complex now provides enough space for the Parliament with no major new building projects foreseen.
