Ancienne prison à Petit Canal, Historical prison in Petit Canal, Guadeloupe, France.

The Ancienne prison à Petit Canal is a ruined stone and masonry building in Petit-Canal, Guadeloupe. Its broad facade is stained with dark mold and green algae over pale gray and ochre surfaces, and the roofline is partially collapsed, exposing rough stonework and gaps. A large, dark, irregular opening with a rectangular stone border occupies the center, and a low, crumbling stone wall runs across the foreground.

The building dates to the colonial period and received historical monument status in 1991 in recognition of its importance to local history. Its role as a prison under French rule made it a symbol of the control systems of that era.

Local tradition holds that the building served as a prison for enslaved people, and that Hégésippe Jean Légitimus, later a Guadeloupe deputy, was held here; the source marks both claims as unverified. A "cursed" fig tree now grows inside the ruin, a detail residents point out.

The ruin stands in Petit-Canal, Guadeloupe, and is inscribed as a monument historique since 1991. The roof has entirely disappeared and only a few grilles remain at the openings, so the structure is unstable. Access to the interior is forbidden for safety reasons; the building can be observed from outside.

Fig trees have rooted deep into the stone walls, with branches and roots penetrating through the original masonry. This plant overgrowth shows how nature is slowly reclaiming the abandoned building.
