## Geography

Gagny is located 10 km to the east of Paris. Until the law of 10 July 1964, the commune was part of the department of Seine-et-Oise. The redivision of the old departments of Seine and Seine-et-Oise then made this commune a part of Seine-Saint-Denis after an administrative transfer that went into effect 1 January 1968.

## History

The priory was founded in the 11th century by Adela of Champagne. Gagny was the fiefdom of Étienne de Gagny, husband of Béatrice de Montfermeil in the 13th century. The priory lasted until 1771, the date de its suppression by the religious authority.
Gagny had several castles, of which the most important, demolished in 1765, belonged to Dominique de Ferrari, Maître d'hôtel ordinaire of the king in 1660. In this park can be found the Saint-Fiacre spring, which supplied water to the park of Raincy at the end of 18th century.
The castle of Maison-Rouge, in the Louis XIII style, was successively the property of Hocquart, marquis of Montfermeil, then in 1845, it belonged to Louis-Philippe, then in 1864 to Michel-Victor Cruchet, a sculptor and artisan from Paris. In 1894, some time after the death of his wife, Michel-Victor Cruchet and his two children sold the Maison Rouge estate to the religious community of the Redemptorists. The Redemptorists then set up a convent there. It was then bought in 1913 by the Boué sisters, dressmakers of renown. Upon the death of the second sister, in 1953, it was acquired by the city. It was devastated at the end of World War II, and the castle was demolished in 1955.
During the French Revolution, the church, after being shut down, was transformed into a Temple of Reason.
Gagny was occupied by Allied troops during 1814–1815, then by the Prussians during the siege of Paris of 1870.
On 20 May 1869, a small part of the territory of Gagny was detached and merged with a part of the territory of Livry-Gargan and a part of the territory of Clichy-sous-Bois to create the commune of Le Raincy.
During the First World War (1914-1918), the taxis requisitioned by Paris and its suburbs assembled in front of city hall. They were charged with taking soldiers to the Front (close to Nanteuil-le-Haudouin) for repulsing the German offensive.

## Economy

On the border of Raincy, old quarries where gypsum was removed since the seventeenth century are still visible. The exploitation of fine plaster, known as "Paris," was the main industry in Gagny until the 1950s. The old Mussat quarries closed down in 1965.
By the end of the nineteenth century, in certain abandoned quarries, mushrooms were already being grown in Paris.
The former gypsum quarries of Gagny were replaced by a large shopping center project, which itself was replaced by the wood of the star, a plantation of trees.
