Avenue Foch of the Service of Promenades and Plantations of Paris, who also designed the Bois de Boulogne, the Bois de Vincennes, Parc Monceau, the Parc des Buttes-Chaumont, and other parks and squares built by Napoleon III. The iron fences and lamps were designed by the architect Gabriel Davioud, who designed all the distinctive ornamental park architecture of Paris during the period, from fountains and temples to gates and fences. The final design consisted of a central avenue one hundred twenty meters wide and 1300 meters long, flanked by sidewalks for pedestrians, riding paths for horsemen, and criss-crossing alleys, shaded by rows
Avenue Foch 140 meters wide. In addition to the four thousand trees that line that avenue, the garden was originally planted with 2,400 different species of trees and plants, making it, as Alphand wrote, "a kind of arboretum." Many of the original trees can still be found in the gardens, including a chestnut tree from India, 4.7 meters in circumference; from 1852, an elm tree from Siberia, 3.8 meters in circumference (1852); and a giant Catalpa tree 3.5 meters in circumference (1852). The gardens contain a monument to their creator, Jean-Charles Alphand, designed by architect Jules Formigé, with sculpture by Jules Dalou.
