What is the name of the historic royal palace located southwest of Paris, known for its Hall of Mirrors?

The historic royal palace southwest of Paris known for its Hall of Mirrors is the Palace of Versailles.

Versailles began as a hunting lodge for Louis XIII, but Louis XIV transformed it into a grand royal residence and the center of French court life. The palace became the principal seat of the French monarchy in 1682, helping Louis XIV project royal power and control over the nobility.

The Hall of Mirrors was built between 1678 and 1681 along the palace’s western side. Its 17 windows face 17 mirrored panels, while ceiling paintings by Charles Le Brun celebrate military victories and the reign of Louis XIV. The hall connects the King’s State Apartments with the Queen’s Apartments.

Versailles is often confused with the Louvre, which is also in Paris but served different roles and is now primarily a museum. The palace also played a major modern historical role: the Treaty of Versailles ending World War I was signed there in 1919, although the ceremony took place in the Hall of Mirrors.
