Paris, France

Designed by I. M. Pei, this striking glass pyramid provides a visual focal point for the Louvre Museum courtyard as well as a modern underground entrance.

Completed in 1900 for the Paris Exposition, the Petit Palais is an opulent building in the Beaux-Arts style. Since 1902 it has been the home of the City of Paris Museum of Fine Arts.

Famed for its stained glass, this beautiful 13th-century Gothic chapel was built by King Louis IX as a royal chapel to house important relics of Christ.

This excellent museum of medieval art is housed in a 15th-century abbot's mansion and includes ruins of ancient Roman baths.

Completed just in time for the 1889 Paris World's Fair, the Eiffel Tower was the tallest structure in the world until 1930. Although unpopular at first, the lacy iron monument has become the beloved symbol of Paris.

Now part of the National Museum of the Middle Ages (Cluny Museum), these ancient Roman baths in the heart of Paris date from the 1st through 3rd centuries and are exceptionally well preserved.
