The chapel of the Torun Teutonic convent was probably built in the 60’s of the 13th century. There is a letter of indulgence from the bishop of Warmia and the papal legate Anselm from 1263, which speaks of an indulgence for all who support the brothers in the construction of a new, expensive chapel.
Undoubtedly, the work on its raising, and especially its finishing, took a long time and could extend even to the 80’s or 90’s of the 13th century. Not only were masses celebrated in the chapel, but also the liturgy of the hours. It included: the summons made at the beginning of the liturgy on a given day, the hour of readings at any time, matins – according to the tradition at sunrise, prayers during the day, evening vespers and the bedtime compass. Brothers who were working or traveling outside the home were exempted from the liturgy of the hours. It was also not valid in the field.
