Île aux Cygnes, Artificial island in the Seine, Paris, France

The Île aux Cygnes is an 850-metre artificial island in the Seine, only 11 metres wide along most of its length, with a paved allée des Cygnes running its full extent between rows of trees. At its north-eastern tip, the belvédère Susan-Travers forms a terrace level with the Pont de Bir-Hakeim, while the lower south-western platform holds the Statue of Liberty replica. Three bridges cross the island: Pont de Bir-Hakeim, Pont Rouelle and Pont de Grenelle.

The island began in 1825 as a dike of the Grenelle river port, consolidated in masonry in 1827 to separate two navigable channels of the Seine. Trees were planted in 1830 by the company holding the bridge, port and station concession. In 1937 the island's surface was temporarily raised from 8,000 to 32,000 m² on pilings for the colonial centre of the international exhibition.

The walkway is named Allée des Cygnes, and the island itself takes its name from an older Île des Cygnes once attached to the Champ de Mars. Since 1878 a public promenade has run its full length, lined with 322 trees of 61 species recorded in 2004, with benches along the way.

The island has three levels: the Susan-Travers belvedere terrace at the north-east end, level with the Pont de Bir-Hakeim and reached by a staircase from that bridge; the long Allée des Cygnes, 11 metres wide, below it; and the lower western platform with the Statue of Liberty, reached by side stairs and linked to the Pont de Grenelle by a sloping central footbridge. The Pont Rouelle crosses overhead.

The statue's tablet reads "IV Juillet 1776 = XIV Juillet 1789", pairing American Independence Day with Bastille Day. In 1998 the 14-ton replica was shipped to Odaiba in Tokyo Bay for the Year of France in Japan and returned the next year. It also appears in the films Frantic (1988) and National Treasure: Book of Secrets (2007).
