With its gilding, grandeur, and lavish ornamentation, Palais Garnier is often compared to the Palace of Versailles. While you can admire the beaux-arts and neo-baroque structure, designed by architect Charles Garnier, from the outside on Paris sightseeing tours, it’s also possible to see the interior by attending a performance or taking a self-guided audio tour or a guided tour of the venue. Book an after-hours tour to explore the Palais Garnier without the crowds. You can also combine a tour of Palais Garnier with visits to other nearby architectural gems, such as the historic Galeries Lafayette department store and the passages couverts (covered shopping galleries).
