The Citadelle Laferrière is a large mountaintop fortress located in northern Haiti, approximately 17 miles(27km) south to the city of Cap Haitien. It is the largest fortress in the Western Hemisphere and was designated by UNESCO as a World Heritage Site in 1982; it is also considered by many to be the 8th man made wonder.

The Citadelle Laferrière has itself become an icon of Haiti and without a doubt the most popular historical attractions in the country.

The threat of the French retaking the island, led to the construction of the Citadelle Laferrière, as a place for the government to retreat to should it become necessary, and to spy any approaching invasion force.  It took more than a decade and the labor of more than 20.000 workers to build this massive fortress.

It is equipped with 365 cannons, in symbolization of fighting for Haiti's independence 365 days of the year; each with a unique, distinctive design; copious amounts of cannon balls are stacked in gigantic pyramids around the compound.

The walls are more than 130 feet tall, and the Citadelle covers an enclosed area of more than 108.000 sq. ft. The foundation of the Citadelle Laferrière are embedded straight into the stones of the mountain. The storehouses and cisterns inside the Citadelle are build to hold enough food and drink for over 5.000 people for a full year and includes special rooms for the king, bakeries and bathing facilities.

The building of this marvelous engineering accomplishment, was done under King Henry Christophe. As a  small mountainous island, King Henry Christophe thought that a massive defense structures overlooking the ports of Cap-Haitien, then Capital of Haiti was necessary to protect the country from French invasion; fortunately, the Citadelle never got used for its purpose as the french never came back to reclaim Haiti.

On a clear day, the coasts of Cuba can be seen from atop the wonder.
