Long before Franciscans lived here, this spot belonged to a different kind of religious community: a house of penitent women, the Büsserinnenhaus, founded in 1383. In November 1384 its administrator, Konrad Schneider — one of the most energetic supporters of the foundation — bought a house belonging to Heinrich von Pottendorf, situated between the Singerstrasse and the Weihburggasse. That house had itself been raised on the site of two older buildings, and he paid around ninety-three pounds of Vienna pfennigs for it out of the foundation's funds. The women, who had until then been housed in the Kumpfgasse, moved here. By 1387 a chapel dedicated to Saint Hieronymus had been built and consecrated by the titular bishop of Castoria. That is where the name on this church was born, more than six centuries ago. The community did not stand still. It was rebuilt in the fifteenth century, with a new dormitory in 1455, and in 1467 the apothecary Ulrich Vogler supervised the building works. In that same year a newly built church — an extension of the Jerome chapel, paid for largely from the foundation of the mayor Konrad Hölzler the Younger — was consecrated by Bishop Albert of Passau. Devotion and money ran together here. Between 1387 and 1511 the community's holdings included a bathhouse called the Perliebin, and Hölzler, who died in 1478, left the women houses and a garden. Their house survived until around 1570.
