The church and the monastery of St. Nicholas belonged to the Dominican Order, brought to Toruń by the Teutonic Order in 1263. The construction of the church was probably completed before 1285. Further construction works were carried out in the 30s of the 14th century. Around 1334-1343 the straight ended chancel was changed to a polygonal one. Buildings were repeatedly damaged by wars, fires and lightning strikes. Survived bombing by the besieged Polish troops in 1658, the Swedish in 1703, and the siege during the Napoleonic wars in 1809 and 1813. When the Order was dissoluted in 1820, in the following years the church was set up as a warehouse and finally demolished in 1834.
The church was a two-nave hall with a polygonally ended chancel. A slightly narrower southern nave was ended by a polygonal chapel of St. Jack from the east. The nave was covered with a common high gable roof, as did the chancel. From the outside, the building’s structure was covered with two-stepped buttresses reaching the crown of the walls, in the chancel set denser than in the nave. In the middle of the eastern top, there was an octagonal turret. From the north to the church was adjacent a monastery with an arcaded cloister on the square plan.
