History
Pontoise is the historical capital of the Vexin français. Its foundation dates from Roman times (Pontisara). At that time, the rock peak overhanging the river Oise supported the defense of the fort which was on the Roman road, the Chaussée Jules César, between Lutetia (Paris) and Rotomagus (Rouen). The road still exists and is now part of the N14 from Paris to Rouen. It is also known to many people as the birthplace of the alchemist Nicholas Flamel.
With an over 2,000 year legacy, Pontoise still has vestiges of the past, such as medieval lanes, convents, churches and museums, and was awarded the "City of Art and History Label" in 2006.
The impressionist painter Camille Pissarro made it famous through many paintings which are present nowadays in the most famous art galleries in the world.

1 This group is made up largely of former French settlers, such as pieds-noirs in 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), as well as to a lesser extent foreign-born children of French expatriates. A foreign country is understood as a country not part of France in 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. 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.
