The church was built by prince Siemowit III and his wife Eufemia of Opava in the mid-fourteenth century, for the Augustinian fathers brought to Ciechanów. At that time it wore the call of Saint Martin. The place for the construction of the church and monastery was given by prince Kazimierz I of Warsaw in 1353. The present church of the Visitation of the Blessed Virgin Mary was built in the first quarter of the 16th century. The temple was destroyed several times, especially in the seventeenth century during the Swedish Deluge. During the reconstruction, the side aisles were pulled down, the arcades were bricked up and the Gothic vault removed, and the pointed windows were replaced by rectangular ones. The Order was dissolved after the January Uprising in 1864. From that time, the church belonged to the parish parish.
The church was built as a brick, Gothic three-aisle basilica (or an aisleless building with two symmetrical side chapels) with a two-bay chancel slightly narrower than the nave, ended with a straight wall. Its high walls were reinforced with buttresses, between which ogival windows were placed. The western facade and the eastern facade were crowned with Gothic gables. On the north side of the presbytery there is a vaulted sacristy with a treasury. A portal led into it, located in a high niche, crowned with a double ogival arch. A similar portal was placed in the entrance to the treasury. The sacristy vault has the form of a four-pointed star with guiding ribs, in the treasury stellar vault is based on arch bands.
