I got off the tram at a stop that was right in front of the European Parliament building.
Luxembourg is a founding member of the European Union, an international organization that allows the free movement of goods, capital and services for the 27 European countries who are members, according to the UK Government website.
Luxembourg is also home to a branch of the European Parliament, which has a number of democratic responsibilities, including passing EU laws and democratic control of all EU institutions, according to the EU website. There are two other branches in Strasbourg, France, and Brussels, Belgium, the website indicates.
Although it is possible to organize free tours of parliament, these can only be arranged for groups of 20 to 50 people and must be booked two weeks in advance, according to the European Parliament website. Therefore, I settled for seeing the exterior of the building.
