The National Home Guard Combat School was inaugurated on 27 June 1943.

[3] In the autumn of 1941, the Home Guard began searching for a central place for training and the then Home Guard chief Gustaf Petri visited, among other places, the manor Vällinge.

The site was found suitable and received permission from, among others, Stockholms vattenledningsverk ("Stockholm's waterworks") to use the buildings and the surrounding land for a symbolic sum of SEK 200 per year.

In March 1942, a call was sent out to companies and certain individuals for grants for the renovation of the school, among other things signed by Crown Prince Gustaf Adolf, and soon SEK 445,000 had been collected.
