Paris-Jardins in Draveil is the site of the 18th-century Château de Draveil, now a historic landmark central to France's pioneering garden city movement. In 1911, the château and its expansive 42-hectare park were acquired by the Paris-Jardins cooperative society, which developed the estate into France's first garden city according to a comprehensive plan by architect Jean Walter. Approximately 320 pavilions were constructed in phases from 1912 to 1914 and again from 1919 to 1933, embodying ideals of community, individual housing, scenic living, and solidarity. The former château now serves as the cooperative's headquarters within this visionary garden city landscape. Protected since 1997 as a heritage zone for architecture, urban planning, and landscape, the estate represents a unique realization of early 20th-century utopian urban design principles.
