From the 11th to the 14th century, the area north of the square was occupied by a small city castle, destroyed in July 1330, by the Teutonic Knights.

After transferring the buses hub to the newly built terminal at Jagiellońska street (Nr.58), the area was rebuilt between 1978 and 1980 into a rectangular shape with flower beds.

In August 2015, the former station pavilion was torn down to give way to a new office building project, Immobile|K3,[5] to be delivered in the first quarter of 2018;[6] works started on June 7, 2016.

1927-1928[9] This building was designed to house personnel of close by shelter for poor infants (at Nr.6),[9] from the director to servants (Polish: służący).

A/1397), December 1, 2008[10] 1908–1909, by Carl Meyer Neo-Gothic The building was erected in 1908, at the initiative of the Patriotic Association of Women (German: Vaterländische Frauenverein), as an Infant Dispensary.

Indeed, in the early 20th century, infant mortality in Bromberg was extremely high (22% in 1928), mostly caused by acute infectious diseases, pneumonia and diarrhea.

The municipality donated the plot of land to the foundation, at the time located on Hann von-Weyhern Platz, next to recently constructed School for girls and Evangelical church.

[11] The main donator (60 000 German gold mark), Julius Berger, expressed the wish to have the facility named after the empress Augusta Victoria of Schleswig-Holstein, as Auguste-Viktoria-Heim.

The facility on Plac Kościelecki, managed by Dr. Hermann Dietz, survived until 1926, when the municipal authorities purchased the property from the Deutscher Frauenverein to create there a shelter for young orphans (up to 2 years old) (Polish: Ochronkę dla Niemowląt).

[11] Personnel comprised in particular six sisters from the Daughters of Charity of Saint Vincent de Paul, five servants, two schoolgirls and later wet nurses.

[11] In 1939, German forces restored the Infant Dispensary in the building, and just after World War II, the edifice resumed its medical purposes.

Ground level openings are round top, main entries are crowned with plaster decoration displaying festoons and angel faces.

Below the middle gable, three symbols recalls the original purpose of the building: a boat (i.e. the shelter'), a cross (i.e. the hospital) and an eagle (i.e. the namesake of the dispensary) Registered on Kuyavian-Pomeranian Voivodeship Heritage List on December 15, 1998[10] 1903, by Heinrich Seeling Neo-Gothic The author of the project was Berlin architect Heinrich Seeling, famous in Bydgoszcz for other realisations, such as the Municipal Theatre, the Church of the Savior, and houses (tenement at Jagiellońska Street 4 or Villa Heinrich Dietz).The reception of the unfinished edifice took place on October 22, 1903.

[15] The designer Carl Meyer has been influenced by the Hanover school of architecture, characterized by brick facades and absence of exterior plaster, decorative sculptures and colored surface.

Carl Meyer also realised several other edifices in downtown Bydgoszcz, among others: The building has a "L" shape with wings, two-storey, a basement and an attic.

The square edifice has five storeys and a usable area of 9000 m2: 6000 m2 for office space, 2400 m2 for retail and service locations, and 80 car parking lots.
