Maubert–Mutualité is a station on line 10 of the Paris Metro in the 5th arrondissement. It is in the heart of the Latin Quarter and Paris' Left Bank.The station is covered in white tiles like most other stations of the Métro, and uses a barrel vault that runs lengthwise over the tracks and platform. However, it is unique in that near the center of the platform two parallel tubes of moving orange lights trace the curve of the vaulted ceiling over the tracks from one side to the other.The station was opened on 15 February 1930 with the extension of line 10 from Odéon to Place d'Italie (now on line 7). It is named after the Place Maubert (Maubert square) and the nearby Maison de la Mutualité.
The Gallo-Roman city of Lutetia (also Lutetia Parisiorum in Latin, in French Lutèce) was the predecessor of present-day Paris.EtymologyThe city was referred to as "Λουκοτοκία" by Strabon, "Λευκοτεκία" by Ptolemeus and "Lutetia" by Julius Caesar. The origin of this name is uncertain.The name may contain the Celtic root *luco-t-, which means "mouse" and -ek(t)ia, meaning "the mice" and which can be found today in the Breton word logod, the Welsh llygod, and the Irish luch.Alternatively, it may derive from another Celtic root, luto- or luteuo-, which means "marsh" or "swamp" and which survives today in the Gaelic loth ("marsh") and the Breton loudour ("dirty"). As such, it would be related to other place names in Europe including Lutudarum (Derbyshire, England); Lodève (Luteua) and Ludesse (France); and Lutitia (Germany).Gallic originsThe oppidum of the Gallic tribe of the Parisii was originally believed to be on the Ile de la Cité from Caesar's Gallic Wars.
