Château de Versailles
Place d'Armes, Versailles
Located on the Western edge of Paris, which requires a brief train trip or drive, Louis XIV's over-the-top pleasure palace is so ridiculously ornate that you'll want to get dressed up for the occasion, if only because every surface is reflective, from the gilded mirrors to the glittery chandeliers. The gardens are just as impressive as the palace, and, in the summer, offer train rides, rowing, and biking. Don’t miss the Petit Trianon, which were Marie Antoinette’s private quarters.
