The park was opened in the year 2000 at Sørenga in what was once the southern part of the medieval city of Oslo.
[1] The park is located within an area which also included the Minneparken and Ladegården on the north side of Bispegata.
Development in the area is prohibited due to ruins and cultural layers above and below ground.
In the west the shoreline meets the park's land area approximately where Oslofjord met Oslo during the Middle Ages (about the year 1300).
[5] Oslo Middelalderfestival and Øyafestivalen were annual events located in the park.
