It takes its name [pleasure boating island] from the land that is surrounded on three sides by the river Seulles and to the east by the harbour basin. "Plaisance" [pleasure boating] because a visionary called Nicolas Hervieux Duclos from 1831 decided that he would make this area a festive and recreational space based on the Grand Tivoli in Paris. This place was thus the stage of a vast project that gave rise to culinary delights as well as recreation park activities in the 19th century.
