The Forum des Halles offers two levels of shopping options, including restaurants, cinemas, an outdoor plaza and more. Located in the heart of Paris, the site has been the center of retail for more than 800 years; and rather than the open-air extravaganza it was in its early years, the shopping complex is now teeming with big-name department stores, boutiques, museums and more. The Forum des Halles is also the largest underground train station in the city, complete with an outdoor park connected to the Forum, making for a great way to relax between merchandise hunting and sightseeing.
