The Beaubourg street is named after the ancient village that belonged to the walls of Philippe Auguste, walls whose ghostly presence still haunts along the boulevards of Paris. Built between 1190 and 1220 the fort was the second and last to have had a defensive function overall, to protect Paris from English attackers during the King's absence gone for the Third Crusade.
The town was poorly attended and its a name, "beau"="beautiful", probably attributed to laugh ironically. In April 1834 a revolt was harshly repressed by General Bugeaud.
This was not the time of the tour of Paris in an old 2CV car along major boulevards. The Beaubourg street, parallel to the Archives street and the boulevard Sebastopol, runs from the Conservatoire National des Arts et Metiers up to the Pompidou Center, which now holds the current plateau Beaubourg.
