Château de Saint-Germain-en-Laye is a royal palace located in Yvelines, approximately 19 km west of Paris, with origins tracing to the 12th century when King Louis VI established it as a fortified hunting lodge. The structure largely dates to the Renaissance reconstruction commissioned by François I in 1539, which preserved the medieval Sainte-Chapelle built by Louis IX around 1238. Louis XIV, born at the château in 1638, made it a primary royal residence before relocating to Versailles. Today, the castle houses the National Museum of Archaeology, one of Europe's largest collections spanning from the Paleolithic period to the Middle Ages, with grounds featuring André Le Nôtre's grand terrace offering sweeping views toward Paris.
