Cité des sciences et de l'industrie Tickets

One of the world's largest and most authoritative museums, the Louvre's magnificent classical silhouette (and funky glass pyramid) are well-known attractions in the center of Paris. But as nice as the Louvre is from the outside, its real magic is in the inside. The Louvre's collection ranges from Mesopotamian, Egyptian, and Greek antiquities, with masterpieces by Da Vinci, Michelangelo, and Rembrandt. With 35,000 works of art (all created before 1848), it's a big, and worthwhile, commitment. The Louvre is one of Paris's Big Three museums; the other two are the Musée d'Orsay (with Impressionist and Post-Impressionist art from the years 1848-1914) and the Centre Pompidou (with 20th-century works created after 1914).

Housed in the stunning Beaux-Arts style Gare d'Orsay railway station, The Musée d'Orsay is home to significant and stunning works by painters including Gauguin, Monet, Manet, Degas, Renoir, Cézanne, and Van Gogh. It's widely considered to be one of the most culturally important museums in the world. Its entire collection is from the period 1848-1914, including many of the most significant Impressionist and post-Impressionist paintings ever created. Chronologically, the works come after those of the neighboring Louvre, and before the collection of the nearby Pompidou Centre.

Europe's largest collection of modern and contemporary art (oh yes, there is a difference!) is housed in a building that was deemed to be architecturally daring in the 20th century. The building features plumbing and piping on the outside and Picasso and Pollock on the inside. And to top it all off, from the rooftop you'll find gorgeous views of Paris and the Eiffel Tower. The Centre Pompidou is one of Paris's 'Big Three' museums – the other two being the Louvre and Musée d'Orsay. The Louvre holds art and artifacts from up until 1848. The Musée d'Orsay contains the world's greatest collection of Impressionist and Post-Impressionist art, all produced between the years 1848-1914. The Centre Pompidou holds 20th and 21st-century works (created after 1914). Altogether, the three museums house a complete timeline of Western art history.

Sainte-Chapelle is a Gothic-style royal chapel, known for its magnificent stained glass windows and for housing the Crown of Thorns. It is located on the Île de la Cité, in Paris.

The Arc de Triomphe is Napoleon's Neoclassical take on the ancient Roman triumphal arch. It's at the center of a square, with a dozen Parisian avenues radiating out from it into the rest of the City of Light. At the base of the arch the Tomb of the Unknown Soldier is rekindled at 6:30 each evening.

This 19th-century architectural masterpiece was built by Charles Garnier at the wishes of Emperor Napoleon III. It's located at the Place de l'Opera, a square in Paris's 9th arrondissement. The insides of the Opéra Garnier boast some stunning Beaux-Arts architecture (the 30-meter high marble Grand Staircase for example). Its intricate interior inspired Gaston Leroux's 1910 novel The Phantom of the Opera (and thus Andrew Lloyd Webber's smash-hit musical), making this the perhaps the most famous opera house in the world.
