Asnières-sur-Seine (French pronunciation: [ɑnjɛʁ syʁ sɛn] ; lit. 'Asnières-on-Seine') is a commune in the Hauts-de-Seine department in the Île-de-France region of northern France. It lies on the left bank of the river Seine, some eight kilometres from the centre of Paris in the northwestern suburbs of the French capital. The area should be reached by Line 15 of the Paris Métro by 2030. The inhabitants are called the Asniérois (masculine) and Asniéroises (feminine) in French.
Goupil & Cie is an international auction house and merchant of contemporary art and collectibles. Jean-Baptiste Adophe Goupil founded Goupil & Cie in 1850. Goupil & Cie became a leading art dealership in 19th-century France, with its headquarters in Paris. Step by step, Goupil established a worldwide trade in fine art reproductions of paintings and sculptures, with a network of branches and agents in London and other major art capitals across Continental Europe as well as in New York City and Australia. Les Ateliers Photographiques, their workshop north of Paris, in Asnières, was instrumental in their expansion from 1869. The leading figure of Goupil & Cie was Jean-Baptiste Adolphe Goupil (1806–1893). His daughter Marie married the French artist Jean-Léon Gérôme.
Paris Métro Line 13 (opened as Line B; French: Ligne 13 du métro de Paris) is one of the sixteen lines of the Paris Métro that are currently open. Built by the Nord-Sud Company as a shuttle servicing both Porte de Clichy and Saint-Ouen from Saint Lazare train station, Line B eventually became Line 13 in 1930, when the Nord-Sud was bought by rival Compagnie du chemin de fer métropolitain de Paris (CMP), while sister lines A became 12, and C the original line 14. Line 13 was extended in 1976 to reach the northern end of Line 14, which it then absorbed. Line number 14, now vacated, was eventually reused for Meteor in 1998.
Line 13 was once planned to be taken over by a north–south RER line connecting the rail yards of Saint Lazare and Montparnasse train stations, but this was cancelled after the reorganisation of the Île-de-France region in 1965. Today, Line 13 connects the western part of Paris to the suburbs of Asnières-sur-Seine, Gennevilliers, Clichy, Saint-Denis and Saint-Ouen-sur-Seine in the north and to Malakoff, Vanves, Châtillon and Montrouge in the south. Serving 32 stations, it is the network's fifth busiest line, with 131.4 million passengers in 2017.
