Originally built as a temporary exhibition for the 1889 World's Fair, today there's no other monument that symbolizes Paris better than Gustave Eiffel's world-famous Iron Lady.

It took almost 200 years to finish this 12th-century Gothic masterpiece immortalized by Victor Hugo and his fictional hunchback. Climb the spiral staircase of the bell towers for a close-up gander at the gargoyles, or have a peek at relics such as the Crown of Thorns in the cathedral treasury.

After a stunted lifespan as a train station constructed for the 1900 World's Fair, this beautiful Belle Epoch building is filled with Art Nouveau objects, Impressionist paintings, vintage photography, and realist sculptures.

The grandest museum in the world started out as a humble fortress in the 12th century, growing in size and prestige as a sumptuous royal palace until the French Revolution gave it a new lease on life as home to the young Republic's art collection.
