Luxembourg (Luxembourgish: "Lëtzebuerg" , French: "Luxembourg" , German: "Luxemburg" ), also known as Luxembourg City (Luxembourgish: "Stad Lëtzebuerg" or "d'Stad ", French: "Ville de Luxembourg" , German: "Stadt Luxemburg" ) , is the capital city of the Grand Duchy of Luxembourg (also named "Luxembourg"), and the country's most populous commune.
 Standing at the confluence of the Alzette and Pétrusse rivers in southern Luxembourg, the city lies at the heart of Western Europe, situated 213 km by road from Brussels, 372 km from Paris, and 209 km from Cologne.
 The city contains Luxembourg Castle, established by the Franks in the Early Middle Ages, around which a settlement developed.
The Communal Council is the body responsible for the civil administration of the four "quartiers" of the Principality of Monaco.
 Because Monaco is both a nation and a city, the council chooses the mayor of Monaco and his/her officers.
 It consists of fifteen members, elected by direct universal suffrage to four-year terms, and a Mayor, selected by the members.
 It meets every three months.
 The main responsibilities of the City Council and the Mayor concern the social and cultural spheres.
 These responsibilities include support for daycares, home care for seniors, and the Academy of music, as well as organization of elections, granting of marriage licenses, and encouraging engagement in the life of the city.
