Departure from Paris
An urban circular walk in search of the French Revolution routes in two Parisian sites: the Bastille, whose capture had a very strong symbolic impact, and the Odéon suburb, where several key figures of the period lived, worked and gathered, including Marat and Danton. It's also an opportunity to discover the signs of other insurrectionary episodes (July 1830, May 1968) and a superb heritage ranging from the Gallo-Roman to the Middle Ages period.
