Wall of the Ferme générale

Unlike earlier walls, the Farmers-General Wall was not intended to defend Paris from invaders but to enforce the payment of a toll on goods entering Paris ("octroi") to the Ferme générale. The wall's tax-collection function made it very unpopular: a play on words of the time went "Le mur murant Paris rend Paris murmurant" ("The wall walling Paris keeps Paris murmuring")[2] There was also an epigram:

Pour augmenter son numéraire (To increase its cash)

Et raccourcir notre horizon (And to shorten our horizon),
La Ferme a jugé nécessaire (The Ferme générale judges it necessary)

De mettre Paris en prison (To put Paris in prison).

Architect Claude Nicolas Ledoux designed its 62 toll barriers in a neo-classical or even classical style.[3] The architecture of the buildings, "dens of the Tax Department metamorphosed into palaces with columns" according to Louis-Sébastien Mercier, highlighted the oppression which the wall represented for Parisians. The wall was bordered by a boulevards outside and a chemin de ronde (a raised protected walkway) inside, except between the barrière d'Italie (now the Place d'Italie) and the barrière d’Enfer (now the Place Denfert-Rochereau) where Gobelins, Saint-Jacques and d'Enfer replaced the chemin de ronde inside the wall.

In 1787, Loménie de Brienne, Minister for Finance, worried about the very high cost of the construction and considered stopping the work but never actually did so because it was so far advanced.

The toll on goods was abolished on 1 May 1791 in the early stages of the French Revolution, but was restored in 1798 by the French Directory. Public perception of the tolls improved under Napoleon. The majority of the toll barriers were destroyed during the expansion of Paris in 1860. At the same time the octroi that had been collected at the wall was abolished.

Some portions of the wall still exist, such as the rotunda of the Barrier of La Villette (now Place de Stalingrad), the Barrière du Trône (now Place de la Nation), the Barrière d'Enfer (now Place Denfert-Rochereau), and the rotunda of Parc Monceau. The wall itself was replaced by the route of the following streets:

• On the left (south) bank of the Seine from the east: Boulevard Vincent-Auriol, Auguste-Blanqui, Boulevard Saint-Jacques, Boulevard Raspail, Boulevard Edgar-Quinet, Boulevard du Montparnasse, Boulevard Pasteur, Boulevard Garibaldi and Boulevard de Grenelle.
