Osternburger Utkiek, Public park in Oldenburg, Germany

The Osternburger Utkiek is a 48-hectare green space on the site of the former Eidechsenstraße landfill in Oldenburg's Osternburg district. Three mounds from waste disposal rise within it, the highest being the Neufeld at 28.15 metres. An S-shaped ridge path links their summits, where pergolas, a heart-shaped climbing element and a partner swing stand.

The park opened in 2009 on the site of a former landfill that operated from 1973 to 2003. This transformation of a waste disposal area into a recreation space demonstrates how old industrial sites can be reclaimed for public use.

The name Utkiek is Low German for "lookout", given to the highest mound of the former landfill, the Neufeld at 28.15 metres. On the two southern mounds, pergolas with seating, a heart-shaped climbing element and a partner swing were installed. Butterfly beds planted with NABU support target the swallowtail.

An S-shaped ridge path links the tops of the three mounds, with gentler paths and a loop path added around them. The grounds can be entered from several sides, but the planned southern entrance has not been built. The fenced gas wells, pump stations and leak-detection installations serve the former landfill and are not open to visitors.

The northern mound, the Neufeld, rises to 28.15 metres, slightly higher than the two mounds of the older Altfeld. Its summit is meant as the actual lookout, or Utkiek, though the planned viewing platform there has not been built. An S-shaped ridge path links the tops of all three mounds.
