2 Best Sights in Western Paris, Paris

This underrated museum has the largest collection of Monet's work anywhere. More than 100 pieces, donated by his son Michel, occupy a specially built basement gallery in an elegant 19th-century mansion, which was once the hunting lodge of the duke de Valmy. You can find such works as the Cathédrale de Rouen series (1892–96) and Impression: Soleil Levant (Impression: Sunrise), 1872, the painting that helped give the Impressionist movement its name. Other exhibits include letters exchanged by Impressionist painters Berthe Morisot and Mary Cassatt. Upstairs, the mansion still feels like a graciously decorated residence. Empire furnishings fill the salons overlooking the Jardin du Ranelagh on one side and the private yard on the other. There's also a captivating room of illuminated medieval manuscripts. To best understand the collection's context, pick up an English-language audio guide (€4) on your way in.

Rising up out of the Bois de Boulogne like a magnificent ship sporting billowing crystal sails, Frank Gehry’s contemporary-art museum and cultural center is the most captivating addition to the Parisian skyline since the unveiling of the Centre Pompidou in 1977. Commissioned by Bernard Arnault (chairman and CEO of luxury-goods conglomerate LVMH), the museum, which opened in 2014, houses Arnault’s substantial private collection, including pieces by Pierre Huyghe, Gerhard Richter, Thomas Schütte, Ellsworth Kelly, Bertrand Lavier, Taryn Simon, Sarah Morris, and Christian Boltanski, among others. La Fondation Louis Vuitton also hosts extensive temporary exhibitions, like the mesmerizing light installations of Danish-Icelandic artist Olafur Eliasson. Le Frank, the pricey on-site restaurant overseen by Michelin-starred chef Jean-Louis Nomicos, is noted for its sophisticated mix of French and international cuisine. The museum is a 12-minute walk from Les Sablons métro on Line 1; alternatively, you can catch the Fondation shuttle (€2 for a return ticket), which leaves every 10–15 minutes from Avenue de Friedland at Place de l’Étoile.
