Fort de Champigny was built following the Franco-Prussian War to defend Paris.

Located to the southeast of Paris in Chennevières-sur-Marne, the fort was part of an outer ring of fortifications built in response to improvements in the range and effectiveness of artillery since the construction of the Thiers fortifications of the 1840s.

It was built in accordance with improved principles of fortification developed for the Séré de Rivières system.

The Fort de Champigny was built between 1878 and 1880 on an area of eight hectares at a location that had been used by the Prussians to bombard Paris in the 1870 war.

During the First World War the fort fired on the Plateau d'Avron with ten guns of 12 and 15 cm caliber.
