Le Marais is a historic district in Paris, France. Long the aristocratic district of Paris, it hosts many outstanding buildings of historic and architectural importance. It spreads across parts of the 3rd and 4th arrondissements in Paris (on the Rive Droite, or Right Bank, of the Seine). Once shabby, the district has been rehabilitated and now sports trendy shopping and restaurants in streets such as Rue des Francs-Bourgeois and Rue des Rosiers. In 1240, the Order of the Temple built its fortified church just outside the walls of Paris, in the northern part of the Marais. The Temple turned this district into an attractive area, which became known as the Temple Quarter, and many religious institutions were built nearby: the des Blancs-Manteaux, de Sainte-Croix-de-la-Bretonnerie and des Carmes-Billettes convents, as well as the church of Sainte-Catherine-du-Val-des-Écoliers. During the mid-13th century, Charles I of Anjou, King of Naples and Sicily, and brother of King Louis IX of France built his residence near the current n°7 rue de Sévigné. In 1361 the King Charles V built a mansion known as the Hôtel Saint-Pol in which the Royal Court settled during his reign as well as his son's. From that time to the 17th century and especially after the Royal Square (Place Royale, current place des Vosges) was designed under King Henri IV of France in 1605, the Marais was the French nobility's favorite place of residence. French nobles built their urban mansions there—hôtels particuliers, in French—such as the Hôtel de Sens, the Hôtel de Sully, the Hôtel de Beauvais, the Hôtel Carnavalet, the Hôtel de Guénégaud and the Hôtel de Soubise, as well as many other hôtels particuliers, found all over the district. During the late 18th century, the district was no longer the most fashionable district for the nobility, yet it still kept its reputation of being an aristocratic area. By that time, only minor nobles and a few more powerful nobles, such as the Prince de Soubise, lived there. The Place des Vosges remained a place for nobles to meet. The district fell into despair after the French Revolution, and was therefore abandoned by the nobility completely, and would remain so until the present day. The Marais is now one of Paris' main localities for art galleries. Following its rehabilitation, the Marais has become a fashionable district, home to many trendy restaurants, fashion houses, and hip galleries. The Marais is also known for the Chinese community it hosts. The community began to appear during World War I. At that time, France needed workers to replace its at-war soldiers and China decided to send a few thousand of its citizens on the condition that they would not take part in the war. After the 1918 victory, some of them decided to stay in Paris, specifically living around the current rue au Maire. Today, most work in jewellery and leather-related products. The Marais' Chinese community has settled in the north of the district, particularly in the surrounding of Place de la République. Next to it, on the Rue du Temple, is the Chinese Church of Paris. Other features of the neighbourhood include the Musée Picasso, the house of Nicolas Flamel, the Musée Cognacq-Jay, and the Musée Carnavalet.
