In the second half of the 19th century the area of the forest began shrinking with the ongoing increased human activity and development.

In 1924, work began in the park to mark out 11 Listopada Avenue and prepare for the construction of a sports field, the grand opening of which took place in 1926.

In 1928, the Białystok City Council was even forced to issue a regulation prohibiting hunting birds that flocked to the park.

In the central part of the park, a monument was erected to the soldiers of the 42nd Infantry Regiment, who died fighting for Poland's independence.

[5] In 1933, on 11 Listopada Avenue, right at its intersection with Wołodyjowskiego Street, a memorial stone was placed in honor of Captain Stanisław Skarżyński, the first Pole to fly solo over the Atlantic.

Further tidying up this area, which had been neglected for decades, in 1935 the former tram depot, which was located at the end of Świętojańska Street, was demolished.

In September 2000, right at the entrance to the park, a boulder-monument was unveiled in honour of the Polish prisoners who were murdered in Katyn forest.
