3 Maja Street is a historical street of downtown Bydgoszcz, Poland, which displays several murals.
 Parallel to the east to Gdańska Street, this south–north path starts from Jagiellońska street, crosses P. Skargi street and ends at the crossroad of Markwarta, Krasińskiego and Staszica streets.
 It borders the western side of the Ludowy Park.
 In the 19th century, the region out of the city of then-Bromberg was devoted to farming. In the 1850s, the new railway track leading to Toruń cut the village of Bleichfelde (today's Bialewy district) into two parts. The southern side was then the target of financial magnates of Bromberg, parcelling out family farms from the newly acquired swaths of land.
 Therefore, in 1851, Karl Hempel, after the death of his father (one of the wealthy investors), took over the Grostwo estate. The latter was quickly renamed Hempels Feld (Hempel's field) and the land was incorporated in 1858, into the Bromberg's territory under this calling, Hempel straße.
 The path is clearly referenced in the maps of the last quarter of the 19th century. For certain periods of time, until the early 1930s, the street had been encompassing a northern extension, nowadays Staszica street. Such was the case: 
 During its existence, the street bore the following names:
 This name commemorates the "3 May 1791 Constitution Day".
 Medical College Buildings, at 13/15 Jagiellońska street
 1850–1852
 Functionalism
 The building was erected between 1850 and 1852, as Bromberg hospital garrison. It was located then at the crossroads of then "Wilhelmstrasse" and "Hempelstrasse". The main building, "U"-shaped, was a monumental edifice of brick facades, with a three-storey body, flanked by 2 avant-corps in its corners: they were higher than the facade and topped with battlements, like medieval towers. Originally the building had a symmetrical facade along a two-storey avant-corps topped with battlements, where was located the main entrance, and three extra barracks for the sick. Additional elements were built regularly until 1910:
 In 1919, with the recreation of the Polish state, city authorities took over the hospital from Prussian militaries. The size of Bydgoszcz garrison and the proximity with the fighting area of Polish–Soviet War increased significantly the activity of the institution: in 1920, under the command of Poznan General District, the medical capacity of the institution reached the maximum amount of 1,140 beds. After the conflict the number of hospitalized patients steadily decreased, with 320 beds (1922), 300 beds (1923) and 200 in 1924–1925. In 1928, Torun military authorities decided to stop the activity of Bydgoszcz hospital, which had only 100 beds left, keeping only the District Hospital in Torun. In this way, Bydgoszcz remained till 1939 without Military medical department.
 During Nazi occupation, the building was used as a German military hospital.
 After the liberation of Bydgoszcz, from 26 January to 10 February 1945, hospital buildings accommodated a Mobile Field Surgical Hospital of the Polish Army. In 1948, a huge renovation occurred: expansion of the main building, demolition five secondary edifices. The renovated complex housed the Provincial Council of Polish Communist Party till the end of the communist era.
 In 1990, the edifice became the property of the Regional Treasure Department: at that time, several buildings passed to the ownership of the Collegium Medicum in Bydgoszcz, which housed here offices of the rector, two deaneries, college administrators, some classrooms, a cafeteria and an additional dormitory. Around 2000, with Tax and Revenue office leaving the premises, the whole building fell under the responsibility of the university.
 From the former buildings of the garrison hospital, only the "U" shaped footprint is left. It was initially constructed in the style of historicism, using forms of Neo-Romanesque. Its appearance resembled a fortress, but these stylistic features have been lost during the complex reconstruction carried out in 1947–1948, which also wiped away the avant-corps, changed the size and shape of the windows, added a fourth floor and extended the gable to the whole edifice.

 End of 19th century
 The building was belonging to the hospital complex built during Prussian period. The ensemble, which survived till today, was referred to as "Garnisonlazaret" ("Garrison hospital"), at "1/4 Hempelstraße". Property of the Collegium Medicum of Bydgoszcz, it houses today a student club.

One can notice arched windows on the ground floor, designed to house shops or restaurant. A small balcony overhangs the corner entry.
 Biziel's tenement house at 8
 1906-1907
 Late Art Nouveau, early Modern architecture
 The first landlord was Leonhard ßech, a foutain builder (German: brunnenbaumeister).

After his demise in 1934, Pelagia, one his three daughters, managed the building till after the Second World War.
 Restored in 2016–2017, the tenement boasts early modernist features. The use of bricks adds to the decoration style. One can notice the presence of an Art Nouveau stucco on the top of the elevation, as well as a double-panel carved wooden door. The back building (at 10) mirrors the same brick-layered style.

House at 11
 1875-1900
 Historicism
 The house is presumably the oldest one standing in the street, as it was initially owned by Karl Hempel who lived then at "53 Wilhelm straße" (present day 22 Jagiellońska street). In 1890, Albert Voigt, a military doctor (German: Oberstabsarzt), moved there. He was serving at the 3rd (Neumark) Mounted Grenadiers "Baron Derfflinger" on "Schubiner straße" (now "Ulica Szubińska").
 After the rebirth of Poland (1920), the landlord was Father Wacław Pacewicz. He was the director of a school for girls at 65 Gdańska street. Two months after the liberation of Bydgoszcz (March 11, 1945) Father Pacewicz was taken to the seat of the Security Office, a building at Markwarta street and was presumably murdered there by the Ministry of Public Security - Ministerstwo Bezpieczeństwa Publicznego.
In the 1930s, the building was managed by the Municipal Treasury (Polish: Skarb państwa).
 The municipality authorities purchased the building in 2017, in order to set up a specialized kindergarten for visually impaired and blind children, as an extension of the main schooling complex located on the abutting plot.
 Although very damaged, one can still notice some wooden decoration on the eaves.

 Early Modern architecture
 First landlord was Otto Krauße, working as an assistant in the postal service.
 The two massive avant-corps are distinctive of the period of construction in the city. One can find same instances at 10 Gdańska street, 18 Paderewskiego street or 28 Swiętej Trojcy street. The arched covering the entrance is also noticeable.
 
Otto Wieze's tenement house at 20

 early Modern architecture
 The first landlord of the tenement at then "24 Hempel straße" was Otto Wieße, a mason and an architect. He was as well the owner of the neighbouring building at 22.
 The damaged building still showcases nice features: a large transom light above the entrance door, original wrought iron fenced balconies, a rectangle bay window and an ogee wall gable topped by spheric pinnacles. The house is planned to be refurbished in 2021–2022.
 The left side wall of the building displays a preserved piece of tiled mosaic characteristic of the 1920s. It is presumably a remnant of an apartment belonging to a demolished abutting house.
 
Otto Wieze's tenement house at 22
 1909-1910
 Early Modern architecture
 Otto Wieße, a mason and an architect, owner of the building at 20, was also the landlord of this edifice. He has been living there till the end of WWI before moving to his tenement at 20.
 Early modernist elements, inspired by Art Nouveau but bare of any superfluous motifs, are incorporated into the facade: a round columned open bay window, loggias and an top arched wall gable. The only compromise is reduced to the entrance door, with stylized columns and a minimalist floral motif frieze in place of the lintel.
 
Tenement house at 24
 1881
 Eclecticism
 This building is the oldest tenement preserved in the street: in the early 1880s, the first owner was a teacher, Emil Knobloch.
 After several change of caretakers, the tenement was purchased in the fall of 1920 by the newly created (July 1919) Polish Red Cross, to set up a "House for the Blind Soldier" (Polish: Dom Ociemnialego Zolnierza), tending for the numerous Polish citizens visually impaired after WWI. 
The place was chosen for its farden and its proximity with already existing specialized institutions (across the street and at 9 Staszica street). The first "pupils" arrived at the house (then at "23 Grodztwo") in January 1921. This institution operated till the start of the Second World War.
 The neo-classical facade was modified in the 1940s to create a ground floor arcade, similar to what happened to other buildings at that time (today at 2 Focha street or 2 Jagiellońska street).
 On a side wall, a mural has been created, entitled "Sportowcy" ("Athletes").

 Building at 2 Markwarta Street, corner with 3 Maja Street
 1939
 Modern architecture
 The plot was purchased in 1938 by the Association of the military disabled (Polish: Związek Inwalidów Wojennych Rzeczypospolitej - ZIW) and the Association of the Blind Soldiers (Polish: Związek Ociemniałych Żołnierzy - ZOŻ) of the Republic of Poland, from a German citizen, Mr. Bohm. The ground floor had a large hall and three rooms, while the upper storeys were supposed to house wounded blind soldiers and orphans children from fallen military. The opening ceremony never happened, as it was scheduled on September 3, 1939, on the first days of WII. 
After the war, both associations (ZIW and ZOŻ) were dissolved by the communist authorities in 1950: the edifice was transferred to the State Treasury. It is still owned by the municipal council. On April 23, 1994, a commemorative plaque was placed on the building to remember its initial role.
