At that time, it was a route leading from Zabłudów towards the Wiesiolowski manor and the parish church in Białystok.

It then lost its character as a public road in the part that entered the palace and park area.

The remaining section of today's Mickiewicza Street, after crossing the gate to Zwierzyniec, passed through the farm buildings and next to the Field of Mars (currently Poniatowski Park), which was the training ground for Jan Klemens Branicki's military regiment.

It became the axis of a separate sector, in which buildings related to the functioning of the state administration were erected.
