# Świętej Trójcy Street, Bydgoszcz

Świętej Trójcy street is a historical street of downtown Bydgoszcz, Poland, bearing several buildings registered on the Kuyavian-Pomeranian Voivodeship Heritage List.

## Location

Świętej Trójcy street follows a quarter of a circle arc, with one tip facing south and the other facing west. It connects Poznańska street to Kruszwicka street and brushes through the area of Mill Island (Polish: Wyspa Młyńska), crossing Kordeckiego street.

## History

Located very close to the old town and its walls, the street is mentioned in early documents from the 1850s. It then developed to actual arc shape, linking at the time Pozener Straße (Poznańska street) to Canal Straße (today's Nakielska street). At that point, the path crossed the Bydgoszcz Canal and extended westward, as Berliner Chaussee (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.
In 1913, the Church of the Holy Trinity in Bydgoszcz, located at then Nr.24 (today Nr.26) has been inaugurated.
A tram line has run in Świętej Trojcy street from March 1898 to September 1970.
Through history, the street bore the following names:
* 1870s-1920, Berliner Straße;
* 1920–1939, Ulica Świętej Trojcy;
* 1939–1945, Potsdamer Straße;
* Since 1945, Ulica Świętej Trojcy (Świętej Trojcy Street).
The current namesake refers to Holy Trinity, hence the patron of the only church in the street.

## Main edifices
### Tenement at 1, corner with Poznańka street

Early 1850s & 1980s
Modern architecture
The earliest address book mentioned in 1855 the landlord of then Posener Straße 337E (later Nr.26) to be Mr Cords, then his widow Bertha in 1864. In the late 1880s, property moved to a merchant and to a vet doctor. In 1910, the new owner, a carpenter, had the house rebuilt: his name was August Kneiding, living at Korn Markt 9, today's Długa street 65. His family possessed it and later lived there till the outbreak of World War II. During the war, a restaurant, the Gaststätte Wendel was located there.
The old Kneiding's house was torn down in the 1980s so the current modern building could be erected.

### Factory building at 2

Early 1950s
Modern architecture
The plot was initially one of the production site of the confectionery firm Jutrzenka. 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. The plant had 12 branches, scattered in downtown old buildings. In the time of the Polish People's Republic, the quality of products was not always high, but buyers were easily found. In 1992, in the realities of the market economy, the company was divided into four independent entities:
* "Modus" Clothing Company in Bydgoszcz;
* "Modina" Clothing Company in Inowrocław;
* "Mikon" Clothing Company in Miłosław;
* "Piła" Clothing Industry in Piła.
On August 1, 1994, the company in Bydgoszcz was transformed into a Joint-stock company and by 2000, the company was restructured by selling redundant real estate, reducing employment. Eventually, in 2005, "Modus" focused on the production and sale of uniforms for the police, the military, fire departments and other services. "Modus" was awarded the 2016 the Forbes Diamond title: it ranked 27th in Kuyavian-Pomeranian Voivodeship with a 41% increase of its value between 2012 and 2014.

### Tenement at 3

1910
German Historicism
In the 1850s the area of Berliner Straße 2 and its surroundings was occupied by an iron foundry factory established in 1846 by Friedrich Eberhardt in Jakob Straße (today Grudziądzka Street). In 1904, a piece of the whole plot was built for Agnes Wiechert the wife of a veterinary surgeon, as Nr.1a. On March 1, 1923, the building housed the seat of the nascent company Eltra established by Stefan Ciszewski, an engineer from Warsaw. In 1992, a wall plaque was unveiled near the porch, to commemorate World War II clandestine armed groups that fought in 1942–1945. Codenamed "3x3", the cell was led by Lieutenant Colonel and intelligence officer Józef Gruss. 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. Józef Gruss was captured by the Gestapo but escaped in January 1945. Arrested after the war by the secret police, he was sentenced to 10 years in prison for conspiracy activities in the Armed Forces. After his release, he lived in this tenement until his death in 1969. In late December 2017, a fire broke out in the attic, destroying most of the wattle and daub gabbles.
The building is an example of German historicism, with a mix of early Art Nouveau elements (curved shapes, round bay windows, floral wrought iron motifs on the balconies) and more ancient styles (Wattle and daub building, tented roof with peak). The most recent renovation (September 2016) restored the gate portal and its transom light.

### Wilhelm Kopp's dye house, at Nr.4/6

1903
Industrial architecture
The first dye house owned by Bydgoszcz industrialist William Kopp was established in 1878 in a nearby street. The company employed just two workers. In 1883, the owner significantly expanded its activity by purchasing a facility in Poznańska street. In 1893, the plant accidentally burned down, due to the misuse of gasoline, which was then used as a cleaning agent.
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. Clothes were coming from several regional office branches to be washed in special washing machines, using gasoline as a detergent that could remove coffee, tea, beer and wine stains. After washing and drying, clothes were ironed and packed. The plant experienced a period of prosperity at the beginning of the 20th century, setting up service points in the city (11 Gdańska street, 12 Mostowa street or 2 Wełniany square) but also in several other cities (Toruń, Inowrocław, Gniezno, Gdańsk, Olsztyn and Chełmno. From 1904 to 1910, the company grew from 32 workers, of whom 26 were women, up to 60 people.
When William Kopp died in 1919, company ownership moved to his two daughters and six sons. In practice, only three sons (Rudolf Wilhelm Albert, Julius Otto Friedrich and Felix Ernst Max) ran the business. The plant successfully operated, under Kopp Family management, through the interwar period and past the German occupation period. After World War II, the factory was nationalized and taken over by state company "Pralchem" but eventually ceased business in the 1990s.
In 2006, the question of rebuilding the dye house into luxury apartments has been raised: such a project would have created around 30 loft houses, an indoor swimming pool and a winter garden overlooking Mill Island, with a 300 m$^2$ service center on the ground floor. However, the plan has never been realized. In 2011, a new owner suggested another project for a 126 rooms hotel with a restaurant, a conference room, a wellness center and a winter garden on the roof to be completed by the end of 2013. This project is currently on hold.
The building has five storeys and an ancillary section. It was constructed in bricks, following the industrial architecture characteristic of the late 19th century. At the lower level were placed dye machinery and steam engine boilers. The upper floors housed laundry facilities, gasoline sewage, ironing area, expedition and housing.

### Tenements at Nr.5,5A,7,9,11

1885
Modern architecture
The area of Berliner straße 2 and its surroundings was in the 1850s occupied by an iron foundry factory established in 1846 by Friedrich Eberhardt in Jakob Straße (today Grudziądzka Street). In particular, it produced in 1857 the steam machine of nearby August Franke's spirit refinery located on Mill Island. After Friedrich, his son Richard, then his wife Amelie took over the lead of the company. In 1900, a sibling, Fritz Eberhardt, was in command of F. Eberhardt company.
Buildings at Nr.5/5A have been designed in the 1930s by Jan Kossowski. In Bydgoszcz, this architect also realized, among others, the Freedom Monument and houses at 5 Ossoliński Alley and 7 Plac Wolności.
The factory worked until the end of World War II. After the war, the plant was nationalized in 1960. It closed eventually in 1994 and was torn down in 2002–2003. Today, a few brick buildings still recall the industrial past, lost among Modern architecture edifices.

### Franz Ciechanowski Tenement, at 23

1903, by Ernst Peter
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. He bought the plot at Berliner Straße 6 in 1896, and had the current tenement built in 1903–1904, by architect Ernst Peter from Berlin. The house is still owned by the Ciechanowski family.
Ernst Peter typically applied Berlin Art Nouveau style: masks, heads, figures, plants and sea waves, atlantes supporting a balcony, slender female figures flanking the entry gate. On both sides of the elevation, at the first level, are scenes depicting workers activities, probably as a reference to Franz Ciechanowski's business. From the outside, the house looks like a palace, but in fact it comprises a string of different habitations. The front elevation is not aligned with its neighbors, since originally there was a small garden, separated by wrought iron fence.
Inside, some of the numerous murals realized in 1907 by Brunon Gęstwicki (1882–1969), Franciszek Ciechanowski's nephew, from Toruń, are still preserved. Originally, the whole staircase, including the vaulted ceiling, was covered with paintings, but many have been lost during renovations. Preserved fragments refer to the Vienna Secession and works from Jacek Malczewski or Wlastimil Hofman. The edifice underwent a thorough renovation in 2020.
