An early 19th century map of Bydgoszcz shows a path roughly matching today's street, which runs through the several estates: Wilczak, Miedzyń and the "Prondy colony".

[4] An 1857 map of Bydgoszcz shows the path beginning at the intersection with Holy Trinity Street (then Berliner Strasse) next to the bridge over the canal,[5] then entering the western suburban city of Prinzenthal.

Through history, the street bore the following names: Current namesake refers to the city of Nakło nad Notecią, 30 km west of Bydgoszcz.

In 1961, the municipal Council extended the city boundaries to include in the west, inter alia, Miedzyń and Jary districts, making allowances for a few thousand plots allocated to individual construction.

In the days of Duchy of Warsaw (1807-1815) Napoleonic General Wincenty Aksamitowski planted rows of trees, today called "William polars", that are recognized as Polish Natural Monument.

[22] In the second half of the 19th century, the park on the canal became a citywide leisure and entertainment area: the first restaurant with a dance floor and a garden patio - Blumenschleuse ("the flower lock")- was built in 1838.

In following years, private entrepreneurs opened there catering facilities and organized attractions: boat rentals, dances, exhibitions, summer theater, ice rink, etc.

In this constant foliage and bushes area was unveiled in 1894 a monument to the co-creator of the canal, Franz von Brenckenhoff, in a form of a bust standing between the second and third lock.

[23] At the same time the Bydgoszcz Canal, was participating actively to the city business: countless rafts floated to the west, and locks were used age by barges, ships and even steamers.

In 1906–1915, a thorough reconstruction of the Bydgoszcz Canal led to excavate a new section (1.63 km long), with two new locks: consequently, the fraction along Nakielska street became abandoned and was used as a recreational area.

A general reconstruction with embellishments was carried out in 1936: in the park, there were a dozen of restaurants, cafes, beer gardens, playgrounds for children, as well as tennis courts, and a 9 ha leisure complex founded in 1928 by Sejm member Idzi Świtała.

[22] The grounds were a propitious place for birds, with a lush vegetation: for 150 years, it has been considered as housing one of the largest colony of Thrush nightingales in Europe.

[25] The park started to become neglected in the 1960s, with the progressive expansion of Bydgoszcz and the unfavorable socio-economic climate: eventually, the old portion of the Canal became filled with rainwater and wastewater from the western part of the city.

A development plan of the Old Bydgoszcz Canal provided for the renovation of hydraulic equipment, the reconstruction of alleys and benches, the construction of playgrounds, and the maintenance of greenery.

Though weathered by conditions, the facade still has visible details including: 1904–1910[19] Eclecticism Initially at Nakeler Straße 3, the tenement was first owned by a merchant, Hermann Blumenthal,[29] and soon (1890) moved to the property of Ferdinand Seegebarth, a retiree, till the end of the Prussian period.

Initially a Municipal School (German: Schulehaus der Gemeinde),[30] it has been working till the start of World War I, during which the building was almost uninhabited (only the rector lived there).

Two gabled avant-corps border the main entrance, the rest of the complex being on the side off street, with several smaller buildings delineating the playing yard.

1907–1908[19] Early Art Nouveau Initially at Nakeler Straße 9, the place was first a store for wood, managed by Hermann Blumenthal Jr.,[33] then in 1900, it was changed to a housing building with the same owner.

The main door is adorned with a stylized female figure with floral and vegetal motifs, in addition to the sun-ray shaped transom light.

At crossing with Wrocławska street, this mural was unveiled in May 2018, part of the annual celebration of the Kuyavian-Pomeranian Voivodeship (Polish: święto województwa).

The renovated facade displays, in a niche on the first floor, a statue holding of the Roman goddess Fortuna with a cornucopia, as an allegory of success and abundance.

[38] The other architectural details left comprise a carved wooden door, some bare cartouches, pilasters and lintels framing windows on the first floor and corbels on the top of the elevation.

Facades on both Nakielska and Czarnieckiego streets have been restored in 2017,[39] and allowed to highlight the rich original architectural decoration, with pediments, bossages or cartouches inherent to this period.

On the massive facade are damaged cartouches, a large vertical motif, the adorned portal and the curved gable mentioning the time of erection.

On the ground floor facade of 35, windows are round-top, and both the main entry and the carriage entrance are delicately decorated with festoons and Art Nouveau–style woman figure.

Today, one can still note part of the vegetal stucco around the main entrance, and the wrought iron balconies protruding from the corner and looking onto Nakielska street.

Cardinal August Hlond issued a decree establishing on 1 October 1946 the Parish of the Divine Mercy ((in Polish) "Kościół Miłosierdzia Bożego").

The front facade has a portal with reliefs depicting Christ the Good Shepherd, and an above mosaic with the image of Our Lady of Czestochowa, the entrance door remained very decorative, with wrought iron hinges and its lock adorned with vegetable motifs.

Inside, since the handover for the Catholic liturgy, one can notice: The upper galleries above the main entrance date back to the original decor of 1905, others have been removed in 1946.. 1878, 1906-1907[19] Eclecticism, elements of Art Nouveau Wilhelm Dettmann, a tax collector, ordered the erection of the building[50] which address was registered as Prinzenthal 47.

[citation needed] The building, designed by architect Alfred Müller, presents typical functionalist style: it survived mainly preserved till today.
