What to do there
3 things to do
Enter the palace (€18 weekdays, €21 weekends, book at chateauversailles.fr). When you reach the Hall of Mirrors, look up: count the chandeliers. There are 20,000+ pieces of crystal. Louis XIV wanted visitors to feel small. Ask yourself: is it working?
Walk to the center of the Hall. Look for the spot where the Treaty of Versailles was signed (June 28, 1919). There's no plaque - the French removed it. But the spot is exactly centered. France forced Germany to sign in the same room where Germany proclaimed its empire in 1871. Revenge architecture.
Louis XIV transformed Champagne from still wine into sparkling wine in the 1690s, drinking it at court every day after monks like Dom Pérignon perfected the méthode champenoise around 1668 to solve exploding bottles in cold cellars. Order a glass of vintage or prestige cuvée at the Versailles wine bar near the King's Bedchamber — you're holding the same beverage that convinced European nobility that bubbles equal luxury. Taste before you sip and notice the mousse (bubble texture): this is 350+ years of French marketing genius that ended the Middle Ages and started French cultural dominance.
Backup:If Versailles café is closed, any Champagne bar in central Versailles (Rue de la Paix) will do. The lesson is the same: you're tasting the wine that ended the Middle Ages and started the age of French cultural dominance.
