We planned our day in Rouen around the walking tour in Rick Steves’ France book. Following his advice we drive into town and parked in the parking lot under the Place de Vieux Marché. This is an ideal location. You come up from the underground parking lot and are standing by the L’Église Sainte-Jeanne d’Arc. We were there on a Sunday, so had the added fun of a farmers market style market at the Vieux Marché
