Saint-Germain-en-Laye (French: [sɛ̃ ʒɛʁmɛ̃ ɑ̃ lɛ] ) is a commune in the Yvelines department in the Île-de-France in north-central France. It is located in the western suburbs of Paris, 19.1 km (11.9 mi) from the centre of Paris.

Inhabitants are called Saint-Germanois or Saint-Germinois. With its elegant tree-lined streets it is one of the more affluent suburbs of Paris, combining both high-end leisure spots and exclusive residential neighborhoods (see the Golden Triangle of the Yvelines).

Saint-Germain-en-Laye is a sub-prefecture of the department. Because it includes the National Forest of Saint-Germain-en-Laye, it covers approximately 48 km2 (19 sq mi), making it the largest commune in the Yvelines. It occupies a large loop of the Seine. Saint-Germain-en-Laye lies at one of the western termini of Line A of the RER.

Saint-Germain-en-Laye was founded in 1020 when King Robert the Pious (ruled 996–1031) founded a convent on the site of the present Church of Saint-Germain.[citation needed]

In 1688, James II of England exiled himself to the city after being deposed from the throne in what has become known as the Glorious Revolution. He spent the remainder of his days there, and died on 16 September 1701.[3]

Prior to the French Revolution in 1789, it had been a royal town and the Château de Saint-Germain the residence of numerous French monarchs. The old château was constructed in 1348 by King Charles V on the foundations of an old castle (château-fort) dating from 1238 in the time of Saint Louis. Francis I was responsible for its subsequent restoration. In 1862, Napoleon III set up the Musée des Antiquités Nationales in the erstwhile royal château. This museum has exhibits ranging from Paleolithic to Celtic times. The "Dame de Brassempouy" sculpted on a mammoth's ivory tusk around 23,000 years ago is the most famous exhibit in the museum.

Kings Henry IV and Louis XIII left their mark on the town. Louis XIV was born in the château (the city's coat of arms consequently shows a cradle and the date of his birth), and established Saint-Germain-en-Laye as his principal residence from 1661 to 1681. Louis XIV turned over the château to James VII & II of Scotland and England after his exile from Britain after the Glorious Revolution in 1688. James lived in the Château for 13 years, and his daughter Louisa Maria Stuart was born in exile here in 1692. James II is buried in the parish church.

Saint-Germain-en-Laye is famous for its 2.4-kilometre (1.5 mi) long stone terrace built by André Le Nôtre from 1669 to 1673. The terrace provides a view over the valley of the Seine and, in the distance, Paris. During the French Revolution, the name was changed along with many other places whose names held connotations of religion or royalty. Temporarily, Saint-Germain-en-Laye became Montagne-du-Bon-Air. During his reign, Napoleon I established his cavalry officers training school in the Château-Vieux.

The Treaty of Saint-Germain was signed in 1919 and was applied on 16 July 1920. The treaty officially registered the breakup of the Habsburg empire, which recognized the independence of Czechoslovakia, Poland, Hungary, and the Kingdom of the Serbs, Croats, and Slovenes (Yugoslavia).[4]

During the occupation from 1940 to 1944, the town was the headquarters of the German Army. [clarification needed]

On 1 January 2019, the former commune Fourqueux was merged into Saint-Germain-en-Laye.[5]

Saint-Germain parish church[edit]

The Church of Saint-Germain

The parish church, which is dedicated to Germain of Paris, was originally constructed in the eleventh century, and the present building (the fourth on the site) was built in the 1820s in a Neoclassical style, with six Tuscan columns supporting a pediment on the main façade. The church houses the mausoleum of James II of England and was visited by Queen Victoria in 1855.[6]

The organ, originally installed in 1698, was rebuilt by Aristide Cavaillé-Coll in the nineteenth century and refurbished in 1903. The church's organists have included Albert Renaud (1891–1924), Albert Alain (1924–1971) and Marie-Claire Alain (1971–2010).
