The nunnery was given large donations and lands upon its foundation by King Magnus III of Sweden.

King Magnus also gave his daughter Princess Richeza Magnusdotter of Sweden to the nunnery.

The St. Clare's Priory had a close cooperation with the Grey Friar's Abbey, Stockholm, and there is an old legend that they were a secret passage between the two convents.

The St. Clare's Priory was to be one of the first convents to be dissolved in accordance with the Reduction of Gustav I of Sweden during the Swedish Reformation in 1527.

Former Abbess Anna Leuhusen and the rest of the nuns was allowed to settle in the Grey Friar's Abbey of Riddarholmen, which had been dissolved the same year left empty by the monks.
