The city of Strasbourg in France is the official seat of the European Parliament. The institution is legally bound by the decision of Edinburgh European Council of 11 and 12 December 1992 and Article 341 of the TFEU to meet there twelve times a year for a session, each of which usually takes about four days. The majority of work, however, takes place in Brussels, and some other work is undertaken in Luxembourg City (see Location of European Union institutions for more information). Also all votes of the European Parliament must take place in Strasbourg. "Additional" sessions and committees take place in Brussels. Although de facto a majority of the Parliament's work is now geared to its Brussels site, it is legally bound to keep Strasbourg as its official home; a situation which garners much criticism from the European Parliament itself, as well as many interest groups, administrative staff, and environmentalist groups amongst others.
