The Blue Paris Métro Line 2 is my link to Montmartre
A short ride from Gare du Nord takes me to Barbès–Rochechouart (through Pigalle, Blance then Place de Chichy

There is a Station for:
Philippe Auguste
Belleville (my unexplored area of Paris) The Triplets of Belleville
Pere Lachaise
Through the busy station at Charles de Gaulle–Étoile near the Arc de Triomphe
