Hôtel de la Marine
This stately Neoclassical palace hides a remarkable 18th-century secret world. The palace is located on the Place de la Concorde, which was previously known as the Place Louis XV and had an equestrian statue of the king (removed during the Revolution).
The Royal Crown Jewels, furniture, weapons, and armor that belonged to Louis XV and his family were moved to the Hôtel de la Marine in 1765. The inside may be visited to see the magnificent 18th and 19th-century decor as well as the views of the Place de la Concorde. The monument's 250-year history is told through a self-guided audio tour. Every day, the Hôtel de la Marine is open. A restaurant, café, and bookstore/gift shop are available. On Fridays, late-night openings are available until 10 p.m. The building's interior courtyard is also available every day from 9 a.m. to midnight.
Address: 2 Place de la Concorde, 75008 Paris
