Terres Basses is west of the small promontory around Simpson Bay. At the end of Marigot Bay Saint Martin's most unknown sight, Bluff Point, rises out of the water. Like some sunken antique building, a few structures peer out above the surface. They remind of the time when the place was still home to a lighthouse and a quarantine office. It was supposed to protect Marigot from imported contagious diseases. The foundation walls are still left, but a closer look will reveal little of interest.
For a long time, Terres Basses itself used to be an almost uninhabited peninsula with only a few huts. However, the land caught the eye of one ingenious American who happened to sail past, and he bought it for some ten thousand dollars. He divided the area into single lots and sold them for a few hundred thousand dollars more. Who or what can be found behind is mostly kept secret. What is known is that there are villas in the most different styles, with one or more swimming pools, guarded by one or more dogs of a sometimes more, sometimes less friendly nature. What they all have in common is the owners' desire for privacy. Every visitor wishing to go to the extremely beautiful beaches here is advised to do so before the evening, when the peninsula's very own security service takes its barrier-equipped control posts into operation.
