Built by Maurice de Sully, Paris bishop, Notre Dame was started in 1163 and finished in 1345. Located on the Cité island and surrounded by the Seine river, Notre Dame is right in the historic district of Paris. 
Of the three rose windows, the two at the transepts, dating to 1250-60, contain nearly all of their original elements, despite an effort in the 17th and 18th centuries to modernize churches and cathedrals in Europe. At that time, windows were broken and replaced with a lightly tinted glass called grisaille.
 

Named after the president who built it, the Centre Pompidou was designed to bring different aspects of contemporary art together in one place. The center houses the National Modern Art Museum, the Public Library of Information, and the Institute of Acoustical Music Research. 
Built inside out, Its normally hidden pipes and frame was put on the outside to provide more interior room for its 25,000 visitors a day. The large red thing in the photo is an escalator.

These various moving fountains and sculptures in the place Igor
Stravinsky (a famous 20th century composer) were designed 
by Niki de Saint Phalle and Jean Tinguely.
The square and the Stravinsky Fountains are in the shadow of the
St. Merry church, shown in the background of this photo, and
across the way from the Centre Pompidou.

The arch, commissioned by Napoléon in 1806, was dedicated to 
the glory of the French Army. Construction restarted in 1825 and was not finished until 1836. 
The arch has been the site of many patriotic occasions, including the ceremonial procession of Napoléon's ashes, the laying in state of Victor Hugo's body, the triumphant march of soldiers on Bastille Day, and the 
burial of the unknown soldier from WWI. 
The arch stands 50 meters tall and 45 meters wide (164 by 148 feet) over 
the Champs Elysées.

The Métro, Paris' subway system, opened on July 19, 1900, its first
line from Porte de Vincennes to Porte Maillot. The system has 124
miles of track, 15 lines, and transports roughly 6 million people a day.
It is smart to keep your ticket with you: should you be stopped by a
métro guard without it, you will be fined 150F ($30 US) in cash only.
Shown in the picture is one of Art Nouveau métro stops designed by
Hector Guimard. Every building is within 500 metres of a métro
station.

The cemetery, created in 1804, was sorely needed to remedy the overcrowding in church and city cemeteries that had become so dire that pressure from all the bodies buried in Cimetiere des Innocents caved in the wall of a neighboring apartment house, overwhelming residents with bones 
and the stench of decaying flesh. 
Some famous people buried there are: Georges Rodenbach, Jim Morrison, Fredéric Chopin, Oscar Wilde, Gertrude Stein, La Fontaine, Molière, 
Alphonse Daudet, Victor Hugo, Marcel Proust, Theodore Gericault, 
Oscar Wilde, Honore de Balzac,Georges Bizet, Jacques Louis David, 
Alfred de Musset, Edith Piaf, and Geoges Seurat.

The building itself was a chateau known as the Hôtel Biron, built between
1728 and 1730. At one time, the artist Auguste Rodin lived there and liked it so much that he made a plan to hand over all of his work to the state on the condition that a museum be made there in his honor. Today the museum houses 6600 sculptures of his, in addition to various paintings, sketches, 
and engravings, and 15 of his mistress' work, Camille Claudel. 
In the garden surrounding the Hôtel Biron are many of his more famous scultptures, including The Burghers of Calais, Balzac, The Thinker and The Gates of Hell.

Giverny is divided into two gardens, the Clos Normand and the 
water gardens. The Clos Normand, created in 1883, is an unorganized, unrestrained garden, the way he liked it; full of flowers, fruit and ornamental trees and climbing roses on iron arches. 
In 1893, Monet bought the neighboring piece of land next to his that would become the water gardens. There you will find the famous Japanese bridge covered with wisteria, weeping willows 
and water lily filled ponds.

Saint Chapelle, under the personal undertaking of King Louis IX, 
was started in 1242 and finished six years later. It was designed to house the relics of Christ's passion, which included the crown of thorns and a portion of the true cross. They were kept and displayed in the apse every Good Friday. 
Saint Chapelle is famous for its stained-glass windows, for which 
two thirds are original. They tell the story of mankind from Creation 
to Redemption, and the story of the relics.                      click on photo

Perhaps the most recognizable landmark in the world, the Eiffel Tower, was started 
in 1887 and finished in 1889. The contractor Gustave Eiffel, with engineers Maurice Koechlin and Emile Nouguier and architect Stephen Sauvestre built the tower for the universal exhibition in celebration of the French Revolution. All the pieces were 
prepared at the Levallois-Perret factory on the outskirts of Paris, where Eiffel's 
company was located. Each of the 18,000 pieces used were designed and 
calculated, traced to an accuracy of a tenth of a millimetre and then put together, 
in pieces of around five metres each. 
The tower has served many purposes in addition to being an exposition observation tower; it was a weather station, radio mast, and site for a wind tunnel.       click on photo
