Rieterpark, City park on a hillside in Zurich, Switzerland

Rieterpark is a landscaped park around three villas: Villa Wesendonck, Villa Rieter and Villa Schönberg. It covers 68,000 m² on the Gabler hill in Enge, rises gently southward from the villas, and on clear days allows views as far as the Glarner Alps. The grounds include a pond and fountain.

Otto Wesendonck bought land on the Gabler hill in Enge in the mid-19th century and had Leonhard Zeugheer design Villa Wesendonck and Theodor Froebel lay out the park, completed in 1855. The Rieter family from Winterthur bought the estate in 1871 and added Park-Villa Rieter; Alfred Friedrich Bluntschli rebuilt the half-timbered house as Villa Schönberg. The city of Zurich bought the 68,000 m² park and Villa Wesendonck in 1945 for 2.9 million francs after a referendum.

The Museum Rietberg housed in the villas displays artworks from Asia, Africa, America, and Oceania that are rarely seen elsewhere in Switzerland. The collection reflects the global importance of non-European artistic traditions.

The park slopes gently upward toward the south, and on clear days the view reaches as far as the Glarner Alps. The grounds are open to the public since the city bought them in 1945. Parts of the tree stock were heavily damaged by Cyclone Lothar on 26 December 1999, so the present planting differs from the original 1855 layout.

The modest half-timbered house where Wagner stayed, built in 1850, was bought by Otto Wesendonck at an inflated price to stop the psychiatrist Ludwig Binswanger from turning it into a psychiatric clinic in 1856. Architect Alfred Friedrich Bluntschli later rebuilt it as Villa Schönberg for Henriette Elisabeth Bodmer-Pestalozzi.
