This typical Montmartre square leads into the rue Poulbot, in reference to Francisque Poulbot (1879-1946), who specialised in depictions of Poulbots, little Parisian titis.

Children played a major role in the Commune. They were traditionally overexploited. Under an 1841 law, they were forbidden to work before the age of 8, but only in companies with more than twenty employees. Very few workshops had more than 20 employees. Working hours were limited to 8 hours for children under the age of 12. Very often, the work to be done was entrusted to families, which meant that children could be exploited within the family unit.

Even if the Commune wanted to send children to school, many of them wanted to get involved in the intense political and social life of the time, and even in its military dimension. During Bloody Week, a battalion of Commune pupils, made up of children as young as 12, occupied the Eugène barracks and defended the Place du Château d'Eau (now the Place de la République) for 36 hours against the Versailles army.

A battalion of the Flourens Avengers, made up of teenagers aged 15 to 17, also defended the Pont Morland to the death.
