Haiti’s Citadelle Laferrière Nears the Finish Line on a 25-Year Conservation Effort
Perched high above northern Haiti, Citadelle Laferrière can feel less like a monument than a feat of will. The Unesco World Heritage Site — listed in 1982 and widely described as the largest fortress in the Western Hemisphere — is now approaching a pivotal milestone: a long-running preservation project, underway for 25 years, is scheduled to wrap up at the end of March.
The citadel was commissioned by Haitian king Henri Christophe and constructed between 1805 and 1820, in the wake of Haiti’s independence. Conceived as a defensive stronghold against the threat of reconquest, it was part of a broader network of fortifications planned along the country’s northern coast. The site’s military logic remains legible today: vantage points designed to scan the sea, and stores of ammunition that still astonish visitors — tens of thousands of iron cannon balls intended for more than 300 cannons made of bronze and iron.
Time, however, has been an adversary as persistent as any invading force. After Christophe’s death in 1820, the citadel was subject to looting, and the earthquake of 1842 compounded structural damage. Over the decades, additional deterioration and episodes of theft have led to restricted areas and heightened concern about safeguarding the site.
The current conservation campaign has been shaped by two urgent priorities: strengthening the fortress against earthquakes and improving visitor access. The World Monuments Fund (WMF), working alongside Haiti’s Haitian Institute for the Protection of National Heritage (ISPAN), has carried out major stabilization and weatherproofing measures. WMF’s work has included waterproofing the structure and constructing a new roof in corrugated aluminum, a process that required extensive planning for the roof framing. Upper portions of the walls — in places rising as high as 45 meters — have also been reconstructed.
In parallel, WMF collaborated with Unesco to bring in an expert to share 19th-century conservation techniques with local workers, linking contemporary engineering needs with historically informed craft.
On site, ISPAN teams have continued the hands-on work of repair and reinforcement: sealing cracks, addressing a balcony, and building small bridges to make circulation safer for visitors. One of the most visible signs of the project has been the steady arrival of wooden planks carried up the mountain. These supports are being installed and then strengthened by injecting liquid cement into the citadel’s walls — a measure intended to reduce the risk of future earthquake damage.
A WMF spokesperson underscored the broader stakes of the effort, emphasizing that “caring for heritage is a shared responsibility,” with governments, communities, cultural institutions, and partners all playing roles in keeping historic places protected and valued.
As the project nears completion, Citadelle Laferrière stands as more than a dramatic destination. It is a living test case for what long-term conservation can look like in a seismically vulnerable region — and a reminder that the material legacy of Haiti’s revolutionary history requires ongoing, collective stewardship.
