Bird's-eye View Of Paris, France

Paris has been a commune (municipality) since 1834 (and also briefly between 1790 and 1795). At the 1790 division (during the French Revolution) of France into communes, and again in 1834, Paris was a city only half its modern size, but, in 1860, it annexed bordering communes, some entirely, to create the new administrative map of twenty municipal arrondissements the city still has today. These municipal subdivisions describe a clockwise spiral outward from its most central, the 1st arrondissement.
In 1790, Paris became the préfecture (seat) of the Seine département, which covered much of the Paris region. In 1968, it was split into four smaller ones: The city of Paris became a distinct département of its own, retaining the Seine's departmental number of 75 (originating from the Seine département's position in France's alphabetical list), while three new départements of Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne were created and given the numbers 92, 93, and 94, respectively. The result of this division is that today Paris' limits as a département are exactly those of its limits as a commune, a situation unique in France.
• Municipal offices
Each of Paris' twenty arrondissements has a directly elected council (conseil d'arrondissement), which, in turn, elects an arrondissement mayor. A selection of members from each arrondissement council form the Council of Paris (conseil de Paris), which, in turn, elects the mayor of Paris.
