Overlooking Marigot Bay sits the imposing figure of Fort St. Louis, the largest historical monument in St.Martin.

Named for the famous crusading king of France, it was originally built in 1767 to protect the settlement at Marigot from foreign invaders. The plans were sent over directly from Versailles at the order of the ill-fated French king, Louis XVI.

Following the events of 1789, the fort was temporarily occupied by the Dutch to prevent the further spread of revolutionary democracy which had reached the island from Guadeloupe. Now, it no longer serves its former purpose, but the steep climb up to the summit provides a panoramic view of the island and the sea surrounding it, and the effort is well rewarded.
