Fodor's Expert Review European Union Quarter
The European Union was born in the embers of World War II, as an antidote to the nationalism that had swept Europe and caused such chaos. Its parliament shifts monthly between Strasbourg (France) and Brussels, where it occupies the Paul-Henri Spaak building (rue Wiertz 43). Hour-long audio-guide tours of Parliament and the Hemicycle, the debating chamber where plenary sessions are held, are available on weekdays (book online). The nearby Parliamentarium visitor center is more accessible and attempts to break down just how the EU works.
