Mazowiecka street is a path in the city of Bydgoszcz, Poland. Its buildings still display a mix of eclectic architectural facades as well as highlight the important urban industrialisation in the history of the city.

A map of Bromberg dated 1876 depicts the pathway, without any naming nor plots. Two years later, the city address book makes the first reference to 8 buildings on Heinestraße. The development of the street has been gradual and eventually achieved in 1910.

The street bore the following names through its existence:

• 19th century - 1920, Heinestraße or Heynestraße. Friedrich Hermann Heyne (1813-1856) was the Bürgermeister of Bromberg from 1845 to 1856, at a time of dynamic economic development, in particular with the opening of the city to the network of the Prussian Eastern Railway.
• German occupation (1939 - 1945), Memel straße, in reference to the Memel Territory (German: Memelland), the northernmost part of the German province of East Prussia.
• 1920 - 1939 and since 1945, Ulica Mazowiecka .

The current appellation refers to the historical region of Mazovia, in mid-north-eastern Poland. It spans the North European Plain, roughly between Łódź and Białystok.

The street follows a approximately east-west path, from Pomorska Street to Aleksandra Fredry street; on the way, it intersects Sienkiewicza, Wileńska and Sowińskiego streets.

1890–1891

Eclecticism, Neoclassical architecture

Initial address was Heinestraße 45, like the tenement at Nr.49, this building was initially the property of the municipality, as Bromberg city apartments (German: Wohnungsverein gehörig). until 1910. This system prevailed, even after Bydgoszcz re-integrated the Polish territory.

The facade of the building, recently renovated, displays nice neoclassical features, mirroring the abutting tenement at Nr.49, with a bit more motifs: pilasters, tympanum on Mazowiecka street and a corner facade with balustrade, topped by round ornaments.

Both buildings have been erected almost at the same period (1890-1892) and have always been owned by one landlord at the time. They had been built for the city (then German) housing cooperative, the Wohnungsverein in bromberg gehörig. In 1920, they were managed by the Polish equivalent structure, the Towarzystwo mieszkaniowe. Some other tenements managed by the city could also be found at 1 Kołłątaja Street or 13/15/17 Zygmunt Krasiński Street.

Both frontages display similar eclectic architectural details, with a slight avant-corps dividing them.
