Situated principally on the right bank of the River Seine, it also includes the west end of the Île de la Cité. The arrondissement is one of the oldest in Paris, the Île de la Cité having been the heart of the city of Lutetia, conquered by the Romans in 52 BC, while some parts on the right bank (including Les Halles included) date back to the early Middle Ages.
It is the least populated of the city's arrondissements and one of the smallest by area, a significant part of which is occupied by the Louvre Museum and the Tuileries Gardens. Much of the remainder of the arrondissement is dedicated to business and administration.
The 1st arrondissement is very small, with a land area of only 1.826 km² (0.705 sq. miles, or 451 acres).
Demography
The area now occupied by the first arrondissement attained its peak population in the period preceding the re-organization of Paris in 1860. In 1999, the population was 16,888, while the arrondissement hosted 63,056 jobs, making it one of the most active for business after the 2nd, 8th, and 9th.
¹This group is made up largely of pieds-noirs from Northwest Africa, followed by former colonial citizens who had French citizenship at birth (such as was often the case for the native elite in French colonies), and to a lesser extent foreign-born children of French expatriates. Note that a foreign country is understood as a country not part of France as of 1999, so a person born for example in 1950 in Algeria, when Algeria was an integral part of France, is nonetheless listed as a person born in a foreign country in French statistics.
² An immigrant is a person born in a foreign country not having French citizenship at birth. Note that an immigrant may have acquired French citizenship since moving to France, but is still considered an immigrant in French statistics. On the other hand, persons born in France with foreign citizenship (the children of immigrants) are not listed as immigrants.
Quarters
Each of the 20 Paris arrondissements is divided into four quarters (quartiers). The table below lists the four quarters of the 1st arrondissement:
