In a medieval will written in 1443 a woman is referred to as a “chapel guardian” in one of the chapels in Strängnäs Cathedral. Only a few other examples can befound, all of them in Stockholm from the 15th and early 16th centuries. The paper shows that these women, in medieval Swedish written records called chapelwomen (kor-käringar), were not cleaning women as previously suggested, as they actually guarded valuable items in the chapels and helped catch thieves. These women seem to have had an informal income from their work, but they were not employed by the churches.
