Marguerite de Valois by Alexandre Dumas — Read

At the period of this history there existed in Paris, for passing from one part of the city to another, but five bridges, some of stone and the others of wood, and they all led to the Cite; there were le Pont des Meuniers, le Pont au Change, le Pont Notre-Dame, le Petit Pont, and le Pont Saint Michel.

In other places when there was need of crossing the river there were ferries.
