During the Belle Époque, seaside tourism and sea bathing developed everywhere on the French coast. Île-aux-Moines was not to be outdone and to follow this movement, hotels were created on the island at the end of the 19th century. The first cabins appeared at that time on the main beach. They are then placed directly on the beach and removed in the low season. Until then, the islanders mainly used the site for collecting seaweed to nourish the fields.
At the beginning of the 20th century, the annex of the Hôtel Petit was one of the first resort buildings to be established on the site and marked the beginning of the urbanization of the main beach.
