City walls of Rocroi

The city walls of Rocroi form a pentagonal fortification with five arrow-shaped bastions surrounded by a moat that protects the town center. Inside, streets radiate outward from a central point, creating a systematic grid of ten main thoroughfares.

The fortification was founded in 1555 under King Henry II to protect the French border against Spanish threats. Military engineer Vauban later reinforced the structures until 1675, transforming it into a model of advanced defensive design.

The walls define how Rocroi looks and functions today, shaping the pentagonal layout that frames daily life in the town. Walking through the streets, you notice how this geometric design remains central to the town's character and spatial organization.

The ramparts can be reached by several walking paths, and guided tours are available if you visit with a group. Walking around the site on foot is the best way to appreciate the geometric layout and see each bastion up close.

The fortification has maintained its original pentagonal shape for centuries despite the changing world around it, making it a rare example of unaltered military architecture. This preservation of the original design is uncommon in modern Europe and offers historians and visitors an unusual glimpse into 16th century planning.
