At that point, the path crossed the Bydgoszcz Canal and extended westward, as Berliner Chaussee[3] (today's Grunwaldzka street).

At the turn of the 20th century, an establishment of leisure with a concert hall called Patzer Etablissement set up nearby the canal, in a green environment.

Early 1850s[1] & 1980s Modern architecture The earliest address book mentioned in 1855 the landlord of then Posener Straße 337E[1] (later Nr.26) to be Mr Cords, then his widow Bertha in 1864.

In 1910, the new owner, a carpenter, had the house rebuilt: his name was August Kneiding, living at Korn Markt 9,[9] today's Długa street 65.

The edifice has been housing the firm "Modus", one of the largest companies in the country, specialized in sewing official and military clothing.

The company was founded in 1945 as a state-owned Zakłady Przemysłu Urządzowego "Modus" (English: Equipment Industry Plants) in Bydgoszcz.

Eventually, in 2005, "Modus" focused on the production and sale of uniforms for the police, the military, fire departments and other services.

[14] On March 1, 1923, the building housed the seat of the nascent company Eltra established by Stefan Ciszewski, an engineer from Warsaw.

[15] In 1992, a wall plaque was unveiled near the porch, to commemorate World War II clandestine armed groups that fought in 1942–1945.

Józef Chyliński was arrested by communist security organs in 1945, and after two years spent in prison, he moved to Canada, where he died in 1985.

Arrested after the war by the secret police, he was sentenced to 10 years in prison for conspiracy activities in the Armed Forces.

1903 Industrial architecture The first dye house owned by Bydgoszcz industrialist William Kopp was established in 1878 in a nearby street.

After 10 years using a temporary place downtown, Wilhelm Kopp had to build a new plant in 1903, on Świętej Trójcy Street, then Berliner straße 33.

In practice, only three sons (Rudolf Wilhelm Albert, Julius Otto Friedrich and Felix Ernst Max) ran the business.

It was ideally situated just across the street, a few meters from his plant producing cast iron and steam powered machines.

The three-storey building, based on a triangular footprint, displays two different brick and plaster facades, with a bay window in the corner and a Mansard roof.

[30] 1888[31] Neoclassical architecture The plot at then Mauß Straße 8 has long been a place for an industrial building related to the nearby foundry complex F. Eberhardt.

[28] 1870[32] Neoclassical architecture Berliner straße 27's first indication dates back to 1872, where the building is mentioned to have Hermann Jacobi, a merchant, for landlord.

The elevation on the courtyard displays an arched passage leading to the main door, protected by a wrought iron gate.

1903,[24] by Ernst Peter[38] Art Nouveau Franz Ciechanowski was an entrepreneur, whose building and engineering company has been thriving, with projects not only in Bromberg, but also in other parts of the German Empire.

[41] 1905[32] Historicism, elements of Art Nouveau The house, initially at Berliner straße 6a was first the property of Johann Ceglarski, a rentier.

She also owned an art exhibition gallery in Bydgoszcz, "Pod Trzynastką" English: Under Thirteen, at Śląska street 13/2.

Registered on Kuyavian-Pomeranian Voivodeship Heritage List, Nr.601222 Reg.A/752, September 20, 1971[43] 1912, by Roger Sławski[24] Modern architecture, Neo-Baroque (interiors) The church was consecrated by Wilhelm Kloske, Gniezno's suffragan bishop on May 18, 1913.

Initially, it was reserved for the use of Polish Catholics, while the Church of the Sacred Heart of Jesus, inaugurated in June 1913 was opened to the German community.

[14] It was bought in the early 1910s by Carl ßeilke, a factory manager, who lived nearby, at Hippelstraße 13 (today's Kordieckiego street 9).

1910[32] Late Art Nouveau, Modern architecture The house, initially at Berliner straße 22b, was owned by Mr Busse, a member of the city council.

The tenement features a mix of styles: late Art Nouveau (adorned Portal, wrought iron gate, eyelid dormer) and early Modern architecture (straight lines, symmetry in the opening's locations).

On both facades, a multitude of adorned motifs recall the late Secession style, echoing the Grawunder brothers' tenements erected at Dworcowa Street 45/47 during the same period.

Registered on the Kuyavian-Pomeranian Voivodeship Heritage List, Nr.601423 Reg.A/1075 (October 27, 1994)[43] 1911-1912[36] Early modernism The house, initially at Berliner straße 22a, was owned by Artur Zemisch, who ran a construction company and lived at Hippelstraße 2 (now 8 Kordieckiego).

[50] The tenement displays noticeable architectural details, from bay windows topped by terrace, to wrought iron and balustrade balconies, to a huge round shape gable crowning the frontage.
