Fort Louis sits on the heights above Marigot on the French side. Archaeologists date it to the second half of the 18th century, and the Collectivité de Saint-Martin has been working to restore it. Here is what is known about the fort, and what to keep in mind before a visit.

When it was built

The firmest dating comes from INRAP, France's national institute for preventive archaeological research. Its 2017 archaeological diagnostic of the site, by Emmanuel Moizan and colleagues, traces Fort Louis from its construction in the second half of the 18th century to its abandonment at the very end of the 19th century.

Local accounts date it to 1789. Local press reports attribute it to the Chevalier de Durat, governor of Saint-Martin and Saint-Barthélemy, and say the fort was built to protect the warehouses of the port. INRAP's report confirms only the broader period, the second half of the 18th century.

What the archaeologists found

INRAP's diagnostic found that the site's archaeological potential is intact. In other words, much of the fort's history is still in the ground and in its walls, and can still be studied.

A protected monument

Fort Louis is one of three legally protected historic monuments on the French side, according to The Daily Herald and Faxinfo. The other two are the former barracks and prison in Marigot, and the Moho engraved rock.

The restoration

The Collectivité de Saint-Martin has run a restoration and development project for the fort since 2017.

Emergency safeguarding works began in 2018, according to The Daily Herald. They were led by Pierre Bortolussi, chief architect of historic monuments, and financed by the Collectivité with support from the Préfecture and DAC Guadeloupe, the regional cultural affairs office.

Visiting

Fort Louis is a protected heritage site, and parts of it may be closed while works are under way. Check access before you go.

Why it matters

For residents of Marigot, Fort Louis is part of the town's history. Its protected status, together with the ongoing restoration, means decisions about the site are made with its heritage value in mind. For visitors, it is a chance to see a fort that was in use from the 18th century to the very end of the 19th.

What this article does not cover

SXM Daily has not yet confirmed the date Fort Louis was formally protected, so that date is left out. We have also left out entry fees, the number of steps to the top and stories of 19th-century battles at the fort, because none of these has been verified.
