The station bears this name after Strasbourg, the Alsatian city, a city symbol of the painful past rivalries that gave its name to recent boulevard de Strasbourg. This vast artery cut by Baron Haussmann, leading to the pier of the same name now Gare de l'Est. But also in Saint Denis, the apostle of Gaul and the first bishop of Paris, who gave his name to his city and its abbey. The street that bears his name leads to the town of Saint-Denis since the Merovingians. Legend has it that he has been martyred, head trench, and his headless body has continued to walk towards the Mount of martyrs (Montmartre). It ends with the door Saint-Denis, built in memory of the triumphs of Louis XIV in Holland and Germany.
