The redoute de Gravelle (Gravelle redoubt) is a fort in Joinville-le-Pont, situated to the south-east of Vincennes in Paris.
Built under Louis-Philippe, from 1968 it housed the École nationale de police de Paris (ENPP), before becoming an illegal immigrants detention centre.
Its south face is decorated with Auguste Arnaud's statue of a skirmisher, formerly placed next to one of a zouave on the old pont de l'Alma, but moved to its present position after the construction of the A4 autoroute in 1973.
The statue is visible from the A4.
