As of 2017, Marigot has 12,000 inhabitants, up from 5,700 in 2006.
Marigot is located on the west coast of the island of St. Martin. It extends from the coast to the west, along the Bay of Marigot and the hills of the interior of the island to the east. On the south-west it is bounded by the Simpson Bay.
Marigot has a tropical savanna climate (Köppen Aw), with very warm to hot and humid weather throughout the year. Rainfall – which is reduced by the rain shadow of the mountains to the east – is not as extreme as in most climates of this type, with the peak occurring from August to November due to hurricanes.
The city is served by Princess Juliana International Airport as well as L'Espérance Airport. There is a ferry to Blowing Point, Anguilla.
Originally a fishing village on a swamp for which it was named, Marigot was made capital during the reign of King Louis XVI, who built Fort St. Louis on a hill near Marigot Bay. Today, that building is the most important in Marigot.
Marigot is typical of Caribbean towns, with gingerbread houses and sidewalk bistros. Market days are every Wednesday and Saturday morning. The crew of the 1997 motion picture Speed 2 shot the finale scene here where the Seabourn Legend hits the island.
