Paris

Refitted under the Second Empire and after the repurchase of the concession by the city, the Saint Martin's day channel is stretched today on 4,5 kilometers including more than 2 kilometers in underground under the boulevard Richard Lenoir and the place of the Bastille.

Situated to Beaubourg in the 4th district, the Centre Pompidou contains the National Museum of Modern Art.
Of the level 0 ( the Forum) at the level 6 (the temporary exhibitions(exposures), the panoramic restaurant), the spaces of the Centre are occasions of meetings with the arts of the 20th century.
Pipes hung on the facade provoked a scandal when the centre Pompidou opened the first time in 1977.
Of the last floor, we can see the roofs of the Parisian buildings.

The churches of St-Eustache and St-Germain l'Auxerrois held the first Parisian marketplace, dating from the beginning of the 12th century. In 1183, Philippe Auguste enlarged the marketplace and built a shelter for the merchants, who came from all over to sell their wares. For centuries, until the marketplace was moved to Rungis, The Halles were the "stomach of Paris". The liveliness once associated with the area has disappeared, even if the new modern shopping mall, the Forum des Halles, still attracts a large number of people.

In the evocation of Montmartre, we think of the numerous artists attracted by the pitoresque site and omnipresent since the end of the 19th century.
From an ethymologic point of view, Montmartre indicates the " mountain of the martyrs ". Before the costruction of the basilica of the Sacred Heart, in a style Byzantine romano, the hill was a small village situated outside surrounding walls strengthened by Paris.
The basilica is the metaphor of the condemnation of the sins of the inhabitants of Paris: sinned which would have caused the defeat of the French army in front of the Prussia in 1870.
