Fort Louis is a former French military fort built during the reign of King Louis XVI of France in the 18th century. Fort Louis was built in 1789 to protect the warehouses of the Marigot harbor, which held locally produced sugarcane, coffee, rum, and salt, against pirates from the Netherlands and the United Kingdom. Because of its deterioration, people made efforts to rebuild it in the nineteenth century. The ruins of Fort Louis are located on a hill in Marigot, France's capital, with views over the Marigot harbor as well as Nettle Bay, Simpson Bay, Galisbay, and Anguilla. Marigot was the battle zone between the French and the English, with the latter arriving from Anguilla (an English colony) to raid the warehouses on a regular basis. This remnant is also one of the most beautiful historical sites in Saint Martin.

Tourists can approach Fort Louis by passing via Marigot's Catholic church and government building, where they will find concrete stairs and a railing at the entrance. After visiting Fort Louis, you can drop by some of Marigot's best restaurants, such as La Terrasse Rooftop Restaurant, Chez Coco Restaurant, and O' Plongeoir Restaurant, all are within 3 miles (5 km) of Fort Louis.

The Mount Vernon Plantation is a plantation in St. Martin that was founded in the 18th century for the purpose of exporting corn, sugar, tobacco, coffee, cotton, and spices to Europe. The Mount Vernon Plantation was established in 1786 and has been carefully maintained over the years by several owners from the United Kingdom, St. Barts, the United States, and St. Martin.

The Mont Vernon Plantation was purchased in 1779 by George Leonard, a British colonist from the nearby island of Anguilla, who built the manor house in 1786. The site was purchased by John Hodge 2nd in 1814, who dubbed the mansion "Mount Vernon," a tribute to the property owned by George Washington, the first president of the United States. Until now, it is one of the most beautiful historical sites in Saint Martin.

Over the years, the Mount Vernon Plantation continues to produce a range of native plants as well as popular local coffees and rums. The property on Mount Vernon Plantation has a unique mansion, the Maison de Maitre (Master's house), which has been rebuilt and is surrounded by tropical fruit trees. The Mount Vernon Plantation first opened to the public in 2005, and visitors can explore the land and learn about its history by using a self-guided cassette player.

The Mary, Star of the Sea Church is a Catholic religious church in the village of Grand Case, in the French section of Saint Martin. As its name suggests, it is dedicated to Saint Mary, Mother of God, in her invocation of Mary Star of the Sea, (Latin: Stella Maris). The church is part of the Catholic Diocese of Willemstad, which is situated on the island of Curacao, and follows the Roman or Latin liturgy. It is easily mistaken for the catholic church of the same name but is located in the Dutch sector of the island.

In 1897, the Mary, Star of the Sea Church began as a modest chapel, which was eventually replaced by a larger construction. Since then, It is also one of the most beautiful historical sites in Saint Martin. In the 1940s, it was built in parallel with the Catholic Church of Marigot (dedicated to Saint Martin of Tours). In 1965, the church was dedicated to St. Mary Star of the Sea. Princess Juliana International Airport is 7.2 miles (11.6 kilometers) away from Mary, Star of the Sea Church. The English language is used for all masses and religious services.
