In every district of Krefeld there are green areas, parks and gardens that are accessible to the public. Most of these areas were created at the time of the Krefeld silk barons. Rich textile manufacturers, such as the von derLeyen and de Greiff families, created the parks for private use. Later, the ownership of almost all of these parks was transferred to the city. They were often equipped with small stately homes or pavilions, which still dominate the townscape today. Many of these architectural legacies are now used for the public good. For example, Haus Sollbrüggen is used today as a music school, while Haus Greiffenhorst houses changing exhibitions by local artists.

In 2002 the city carried out major redevelopments of the parks as part of the „Euroga 2002 plus" State Garden Show, returning them to their historical original condition with loving attention to detail. Properties which are now included in the „Route of Horticultural Art between the Rivers Rhine and Meuse (Maas)" are, the gardens of Haus Esters and Haus Lange, Linn Castle Park, Greiffenhorstpark, the Landscape Park and Heilmannshof Arboretum, Schönhausen und Sollbrüggen Park, Schönwasserpark and Stadtwald.
