Today is France’s national holiday, known abroad as Bastille Day, and perhaps you have wondered: what became of all that stone after the goliath Bastille prison was stormed on July 14, 1789? One enterprising man named Pierre-François Palloy, who participated in the siege, almost immediately took charge of the building’s demolition, and transformed a large quantity of its rubble into souvenirs of the uprising.

The Musée Carnavalet in Paris houses one of these relics: a miniature Bastille made from stone from the prison. It’s one of 83 models that Palloy sent out to France’s newly formed departments, which divided the country into new bureaucratic regions. The earliest models were carved right from the rock, while later mini Bastilles were made by casting pulverized stone. Along with paintings, etchings, and other visual representations, these building miniatures provide a material link to the moment when the mighty stone towers that had represented oppression by the monarchy became the ultimate symbol of the French Revolution. (Even though the Bastille was only holding seven prisoners at the time.) The tiny Bastilles, with their towers and carved windows, were just one component of Palloy’s salvaging activities. He also melted prisoner chains into medals, etched plaques into stone, and even gifted a prison key to George Washington through the Marquis de Lafayette, which is now on view at Mount Vernon.

Some small Bastilles have disappeared over time, but others are on view at museums such as the Musée Départemental des Antiquités in Rouen and Jeu de Paume in Versailles. The Bastille in a way is still very much a part of Paris, where huge quantities of its stone were reused to build the Pont de la Concorde bridge, while vestiges of the building unearthed in 1899 are on view at the Boulevard Henri IV, and others in its subway stations.

In a 1792 speech, Palloy reportedly said: “France is a new world and in order to hold on to this achievement, it is necessary to sow the rubble of our old servitude everywhere.” These Bastille maquettes helped cement the fallen icon of past control as a symbol of new liberty.
