Rocroi (pronounced as /fr/) is a commune in the Ardennes department in northern France.
The central area is a notable surviving example of a bastion fort.
Rocroi was fortified by Francis I of France and expanded by Henry II of France. Because of its strategic location in the north of France it changed hands a number of times during wars. It is best known for the Battle of Rocroi in 1643. In the 1670s the fortifications were re-modelled by the French engineer Vauban.[2]
In 1815, two months after the Battle of Waterloo, the town was taken by Prussian and British forces (on 16 August).
