In May 1919 the village was included in Greater Białystok and designated as "garden city" which was then divided into building plots in 1925, an official colony.

The Central Square of the Garden City is located at the intersection of Pułaskiego Streets (then Żurawie), Wspólna and Strzelecka.

The area of the modern Nowe Miasto district was defined by the City National Council resolution in Białystok of November 31, 1959 on the establishment of the districts of the city of Białystok: composed of Nowe Miasto, Swoboda, Bażantarnia and the former village of Starosielce.
