[2] In 1363, Knight Commander of the Teutonic Order, Giselbert von Dudulsheim, resolved the discord by assigning St. John's under the leadership of St. Catherine's Church.

[6] Since 1453, the Teutonic Knights restricted the height of all church and secular towers in proximity to their castle at the River Motława (Mottlau), in case of a ranged attack.

[7] By the decision of Jan Gruszczyński, Bishop of Kuyavia, St. John's became its own parish church in 1456 when Danzig/Gdańsk turned to the Polish Crown during the Thirteen Years' War.

[4] Notably, the building's foundations became unstable and walls tilted due to the presence of groundwater and wet soil resulting from its closeness to the nearby river.

[4] Following the war, the church was briefly utilised as a lapidarium – a storage facility for any noteworthy stone fragments that were excavated in the rubble of old Danzig, now Gdańsk.

[13] The interior is adorned by several ornamental altars, epitaphs and commemorative tablets of noble individuals, though their number is small and the overall inside appearance is bare due to wartime destruction and current purpose.

[14] For example, the artist Abraham van den Blocke created a monumental Late Renaissance altarpiece dedicated to John the Baptist, which was restored in the aftermath of World War II.
