Marseille (French: Marseille; Provençal Occitan: Marselha; see below) is a city in southern France, the prefecture of the department of Bouches-du-Rhône and of the Provence-Alpes-Côte d'Azur region. Situated in the Provence region, it is located on the coast of the Mediterranean Sea, near the mouth of the Rhône river. Marseille is the second-most populous city in France, after Paris, with 877,215 inhabitants in 2022 (Jan. census) over a municipal territory of 241 km (93 sq mi). Together with its suburbs and exurbs, the Marseille metropolitan area, which extends over 3,972 km (1,534 sq mi), had a population of 1,900,957 at the Jan. 2022 census. The cities of Marseille, Aix-en-Provence, and 90 suburban municipalities have formed since 2016 the Aix-Marseille-Provence Metropolis, an indirectly elected metropolitan authority now in charge of wider metropolitan issues, with a population of 1,922,626 at the Jan. 2022 census.

Founded c. 600 BC by Greek settlers from Phocaea, Marseille is the oldest city in France, as well as one of Europe's oldest continuously inhabited settlements. It was known to the ancient Greeks as Massalia and to Romans as Massilia. Marseille has been a trading port since ancient times. In particular, it experienced a considerable commercial boom during the colonial period and especially during the 19th century, becoming a prosperous industrial and trading city. Nowadays the Old Port still lies at the heart of the city, where the manufacture of Marseille soap began some six centuries ago. Overlooking the port is the Basilica of Notre-Dame-de-la-Garde or "Bonne-mère" for the people of Marseille, a Romano-Byzantine church and the symbol of the city. Inherited from this past, the Grand Port Maritime de Marseille (GPMM) and the maritime economy are major poles of regional and national activity and Marseille remains the first French port, the second Mediterranean port and the fifth European port. Since its origins, Marseille's openness to the Mediterranean Sea has made it a cosmopolitan city marked by cultural and economic exchanges with Southern Europe, the Middle East, North Africa and Asia. In Europe, the city has the third largest Jewish community after London and Paris.

Henri-Jacques Espérandieu (French pronunciation: [ɑ̃ʁiʒak ɛspeʁɑ̃djø]; 22 February 1829 – 11 November 1874) was a French architect who made his career in Marseille. He was responsible for some of the city's now most famous buildings, including Notre-Dame de la Garde (the "Bonne Mère"), Marseille Cathedral (the "Major") and the Palais Longchamp.
