Louis XIII wall

Walls of Paris (enceintes de Paris or murs de Paris in French), refers to the city walls that surrounded Paris as it grew from ancient times until the 20th century, built primarily to defend the city. Several successive city walls were built, with the exception of 1670, when Louis XIV ordered the demolition of the Louis XIII Wall, through 1785, when construction began on the Wall of the Farmers-General. The city walls of Paris include:

As Paris expanded over time, new walls were built to consolidate the existing city with new houses, gardens, and vegetable fields. Existing walls would eventually be destroyed and its site built up into a street or boulevard. Only a few sections of the Wall of the Farmers-General (pavilions of Claude Nicolas Ledoux) and the Wall of Philippe Auguste survived. The walls' influence on modern Paris can still be seen on some of its major streets and boulevards such as:

Before its occupation by the Romans, Lutetia lacked proper defenses and was therefore partially demolished at the beginning of the Roman occupation. The first wall of Paris was probably built by the Gauls on the river Seine, although its exact location is unknown. In his Commentaries on the Gallic War, Julius Caesar wrote: "Id est oppidum Parisiorum, quod positum est in insula fluminis Sequanae", indicating that Lutetia (former name of Paris, the town of the tribe of Parisii) was a fortified camp on an island. The relationship between this island and the Île de la Cité has not been demonstrated, and excavations have not uncovered anything earlier than Augustus. This is also unclear due to the discovery in 2003 of the remains of a city on a site now occupied by Nanterre.
