Norsborg was previously a country estate in the Botkyrka parish, situated on a bay of Vårbyfjärden and with some of the property facing Bornsjön, as well as Kärsby and Tomtberga with an area of 350 hectares.

The area, which was originally called Borg and was part of the village of Hundhamra, but in the late 1700s the property was named Norsborg after the owner Count Johan Liljencrantz's wife Eleonora Stjernstedt.

[1] Liljencrantz also owned Sturehov, Slagsta farm and Fittja in the same parish and had Norsborg's manor built.

From his time a significant part of the garden and the large English-style park originate with a gazebo by Olof Tempelman and a view tower that long adorned Norsborg.

The city built their main station of the management, Norsborg waterworks, with filtration basins, pumping stations, electricity plants, residential buildings and more, and in 1912 the city council decided to place the entire water main plant there.
