Le Musée Territorial, Wall House
On the far side of the harbor known as La Pointe, the charming Municipal Museum on the first floor of the restored Wall House has watercolors, portraits, photographs, traditional costumes, and historic documents detailing the island's history over many hundreds of years, as well as displays of the island's flowers, plants, and marine life. There are also changing contemporary art exhibitions. It's a must-stop on your St. Barth visit, and it's free.
