Białostoczek can be seen on city maps from the times of Jan Klemens Branicki. It is already marked on the "Plan du chateauet de la ville de Bialystok" from around 1771. As "Bialystoczek" it is present on the map of New East Prussia from 1808, as well as the tsarist military plan of Bialystok from 1886. Białystok was not included in Białystok until May 10, 1919. On the plan of Białystok from the 1930s, but also from 1966 there are only a few streets in the place of today's housing estate: Białostoczek, Zagumienna, Kozłowa, Radzymińska, Suwalska, Sitarska, Bielska, Hajnowska and Sokólska. The latter, however, has a completely different course. From the Avenue of the Millennium of the Polish State to Zagumienna, it coincides with our modern street, but later it turns south and ends in the place of today's roundabout of priest Zbigniew Krupski. On the plan from 1966, two colonies are also marked: Białostoczek I and Białostoczek II lying north of the intersection of Tysiąclecia Avenue of the Polish State and Sokólska Street.
