Presentation of the City

Castle of Saint-Germain-en-Laye
Castle of Saint-Germain-en-Laye

Saint-Germain-en-Laye is a city steeped in history and culture that is the birthplace of King Louis XIV. Its castle, as well as its terrace designed by Le Nôtre overlooking the Parisian valley, is one of France’s most beautiful royal residences. Molière created the King’s Troup here in 1665. Oak trees dating back to the reign of Louis XIV can be admired in the national forest, our city’s jewel covering more than 3500 hectares.

This rich history is nonetheless not the only appeal our city holds, for we are steadfastly focused on innovation and characterized by a high quality of life.

At the heart of Yvelines, in proximity to Paris, Hauts de Seine, Val d'Oise and Normandy thanks to a dense transportation network (RER line A, the nationale 13 and 184 trunk roads, bus 258 Paris-La Défense), Saint-Germain-en-Laye is home to the headquarters of international companies, as well as a number of outstanding public and private schools (20,000 students enrolled). The international school of Saint-Germain-en-Laye, which hosts 2,800 multilingual pupils enrolled in kindergarten to sixth form, contributes to its international reputation. Finally, its protected city centre is considered the largest open air shopping area in western Paris.
