Etterstad (pronunciationⓘ) is a neighborhood in Oslo, located between the river Alna and Strømsveien, north of Vålerenga.
In 1821, King Charles XIV John ordered an exercise with 6,000 soldiers as a political power demonstration aimed at the newly formed parliament.
The field was also the site of executions, the last performed on 19 April 1864 on the Prussian Friedrich Wilhelm Priess and the Dane Knud Fredrik Christian Simonsen by Samson Isberg with an audience of 5,000 people.

This was permitted in 1922, and Oslo Bolig- og Sparelag started construction in the 1930s in a large reconstruction of all property down to the railway station.
