This week we're up on the hill of Montmartre, as we put the focus on a little-known, yet defining chapter of French history: the Paris Commune. Walking around the picturesque area today, there’s little trace of the chaotic and deadly scenes that played out here just 150 years ago: a brutal civil war that came hot on the heels of a deadly Prussian siege. We look back at the Paris Commune and explore its legacy today. We also hear from historian Ludivine Bantigny.
