The Main Town charter (Handfeste) of 1342/43 designated a plot of land two "Seile" (a historical unit of measurement) long and wide for St. Mary's Church and its churchyard. In addition, the parish itself was to be endowed with a plot the size of one of the largest homesteads.

Since the church is already mentioned in 1271, it seems likely that these provisions were made when St. Mary's Church became independent from St. Catherine's Church, to which it had previously been subordinate. In the land registers, this endowment of the parish is listed as "locus dotis" (endowment site). It was bounded by the Main Town's meat stalls (Fleischbanke), the Heilig-Geist-Gasse (Holy Spirit Lane), the Kleine Kramergasse (Small Shopkeepers' Lane), and the narrow passage between the parish grounds and the church.

On the front portion of the parish plot, facing the Heilig-Geist-Gasse, the Royal Chapel was built in 1678. The name "Am Pfarrhof" (At the Parsonage) was also used occasionally. Today the former Pfarrhof forms part of the lane called Plebania, which translates as "rectory."
