 The far end is defined by the hemi-cycles of colonnades that enclose the sides and are carried across the pre-existing façade of the "Palais du Gouvernement".The four corners and the west and east sides of the square feature gilded wrought iron gates and lanterns, created by Jean Lamour (1698–1771); who was also responsible for the wrought iron balustrade on the main staircase in the Hôtel de Ville, and the balcony across the centre of its main façade.The north-west and north-east corners also feature ornate fountains designed by Barthélémy Guibal (1699–1757).
