Boulevard de Magenta
It is named after the battle of Magenta, a battle fought on 4 June 1859 near Magenta in Italy. It was a victory by the Piedmontais of the kingdom of Piedmont-Sardinia and by the French armée d'Italie under general Patrice de MacMahon and Napoléon III over the Austrians under Guylay. The creation of the boulevard de Magenta was part of the Hausmannian transformation of Paris. It was completed in 1855 between rue du Faubourg-Saint-Martin and the boulevard de Rochechouart (the boulevard here in fact follows the route of the old rue du Nord which formed a part of an 1827 subdivision) and in 1859 between place de la République and rue du Faubourg-Saint-Martin. The RER station Magenta is located to the east of the gare du Nord and named after this boulevard, even if it is not truly under it. It is served by RER line E.
