The park's name is an acronym for the 'Oberhausener Landesgartenschau' (State Garden Show), which was held there in 1999.
The park was constructed on land that was formerly used by the Concordia coal mine, which closed in 1968.
It is connected to the Emscher Park cycling path network, which links numerous industrial heritage sites across the Ruhr region.
The park includes a dedicated high-ropes course known as the Tree2Tree forest park.
Significant portions of the landscape were re-contoured to create mounds that act as sound barriers for concert events.
The park's design intentionally incorporates rusted metal and concrete remnants to honor the site's industrial past.
OLGA Park is a sprawling 26-hectare landscape park located on the former site of the Concordia coal mine in Oberhausen. It serves as a central hub of the Emscher Landscape Park network, repurposing industrial heritage for recreational use. The park features a large multi-purpose field, a high-ropes course, and paved cycling and walking paths. It is known for hosting large-scale music festivals and open-air concerts throughout the year. The site preserves several industrial relics, including the old mine’s compressor hall and remnants of structural foundations. Extensive landscaping has integrated steep grass slopes and artificial mounds into the flat industrial terrain. It remains a key green corridor connecting the city center to the surrounding Emscher region.
