The Château-Neuf or New Palace of Saint-Germain-en-Laye was built starting in 1556 and served as a royal palace for over a century. It was a huge palace in its day, but large parts of it were demolished in the 18th century. Now one of the few remnants, the Pavillon Henri IV, is used as a restaurant.

Louis XIV was born here
In 1638 King Louis XIII (= the 13th) and his wife Anne of Austria (who despite her name was more Spanish than anything else) finally managed after twenty-two years of unhappy marriage to produce a male heir, Louis-Dieudonné (Louis the God-given), who was born in the Château-Neuf. Five years later Louis XIII died, also in the Château-Neuf, and his young son became King Louis XIV (= the 14th).
Unlike his father (but like his grandfather Henri IV), Louis XIV turned out to be a prodigious womanizer who fathered six legitimate children by his Spanish wife Maria Theresa and numerous illegitimate children by a succession of glamorous mistresses. He reigned for 72 years, until his death in Versailles in 1715.
