Vadstena adliga jungfrustift

Vadstena adliga jungfrustift or VAJS, was a Swedish foundation to support unmarried female nobles.

The original purpose was the foundation of a Protestant convent for unmarried female members of the nobility at Vadstena Castle.

It was to be both a school for girls from the nobility, as well as a home for poor noblewomen who were unable to support themselves.

However, from 1747 onward, it started to accept members, which were given the title stiftsfröken and received an allowance from the foundation, though they never lived at the Vadstena Castle.

In 1758, it was formally transformed into a fund for the support of unmarried female members of the nobility, who also used the title stiftsfröken.
