The Garden District is a neighborhood of the city of New Orleans. A subdistrict of the Central City/Garden District Area, its boundaries as defined by the City Planning Commission are: St. Charles Avenue to the north, 1st Street to the east, Magazine Street to the south and Toledano Street to the west. The National Historic Landmark district extends a little further. The area was originally developed between 1832 and 1900 and is considered one of the best-preserved collections of historic southern mansions in the United States. The 19th-century origins of the Garden District illustrate wealthy newcomers building opulent structures based upon the prosperity of New Orleans in that era.
