 The Musée du quai Branly is located on it.It was formed by the merger of the islets known as île des Treilles, île aux Vaches, île Maquerelle, île de Jérusalem and île de Longchamp, and was merged into the "rive gauche" of the Seine at the end of the 18th century.An oak pirogue, built with fir plugs, discovered in August 1806 during the construction of the footings for Pont d'Iéna, was thought to be a Norman boat dating to the Siege of Paris in 885/86, although some scholars believe that it may have dated to the Sequani tribe from the first century B.C.
