Pavillon de Paris * * * *

Madeleine Church:
The neo-classic church of Sainte Marie Madeleine is in the north of the Concorde Square at the end of the Royal street. Built in the style of the Greek Temples, it was devoted in 1842 after almost a century radical modification and delay of construction.
The monumental staircase in southern part offer one of the most beautiful perspective of Paris, along the Royal street, through the Concorde Square, crossing the Seine, to the National Assembly.

 
Opéra Garnier: the older of the two main opera houses in Paris. It was designed by Charles Garnier, hence the name; the other, newer opera house was built on the site of the Bastille, and is thus called the Opéra Bastille.
 

The Louvre Museum:
This is one of the largest and most famous museums in the world. The building, a former royal palace, lies in the centre of Paris, between the Seine river and the Rue de Rivoli. Its central courtyard, now occupied by the Louvre glass pyramid, lies in the axis of the Champs-Élysées, and thus forms the nucleus from which the Axe historique springs. Part of the royal Palace of the Louvre was first opened to the public as a museum on November 8, 1793, during the French Revolution.

The Eiffel Tower was built for the International Exhibition of Paris of 1889 commemorating the centenary of the French Revolution. The Prince of Wales, later King Edward VII of England, opened the tower. Of the 700 proposals submitted in a design competition, Gustave Eiffel's was unanimously chosen.

However it was not accepted by all at first, and a petition of 300 names  including those of Maupassant, Emile Zola, Charles Garnier (architect of the Opéra Garnier), and Dumas the Younger - protested its construction.

At 300 metres (320.75m including antenna), and 7000 tons, it was the world's tallest building until 1930.
