Many monuments and sculptures decorate the Alsterpark on the meadows and paths around the shore. Some are from the aforementioned exhibition "Sculpture in the open air", others from the "Art in public space" program. Well-known works are: "Four men on buoys" by Stephan Balkenhol from 1993. One of his figures is on the Alster at Schwanenwik. The bronze "Children flying kites" from 1963 is by Gerhard Brandes. The "Large standing figure" from 1958 is by Jörn Pfab. The two-part sculpture "Orpheus and Eurydice" is from 1958 by Ursula Querner. Metal thieves stole Eurydice and the sculpture was incomplete for a long time and became known as art theft. On the Alte Rabenstraße there is a street sign with a raven sculpture from the 19th century on a frame. The sculpture is by Franz Andreas Meyer. Manfred Ritthoff-Linau's sculptures are "With a view of the lake" from 1991, "The guardian of the swamp" from 1993 and "The stranger by the water" from 1995. His sculptures are all located on the eastern bank of the Alster. In October 2021, animal rights activists erected a memorial for the victims of animal testing around the world. The animal sculpture of the "Hamburg Town Musicians" was located on a meadow in the Uhlenhorst district at the Schöne Aussicht. For safety reasons, the memorial has since been moved to a pedestrian zone in the Altona district.
