The park-like Zorgvlied Cemetery is located on the left-bank of the Amstel river, south-east of Amsterdam's city center. It was opened in 1870 and, due to its popularity, has been expanded three times (1900, 1919, 1926). Many Dutch celebrities are buried here. The cemetery -- park and paths -- as well as a number of burial sites in the cemetery are on the list of Rijksmonuments -- monuments deemed to be of Dutch national importance. Although unique monuments can be found though-out the cemetery, in the early 1990's the "Paradiso" area of the cemetery was set aside for monuments of extraordinary size or appearance.
