[1] Grodzka Street buildings vary greatly one from the other, beginning with the three historic granaries from late 18th century, to the all-glass similar-shape modern mBank in Bydgoszcz, which became an icon of Polish architecture.

The area has been the focus of numerous archaeological excavations, which has intensified since the 1990s, providing a huge amount of information on various aspects of settlement and development of Bydgoszcz.

First comprehensive archaeological searches conducted in the 1990s led to the discovery of large-scale relics related to the first footprint of Bydgoszcz settlement, with its castle built on an island formed Brda river meanders.

It has unveiled wooden joists piles set on a NE-SW track, interpreted as remnants of a wood surface of today's Kreta street.

In 15th and 16th centuries, on the western end of the street was built a bridge connecting to Mill Island in Bydgoszcz, located at Farna weir: it has been demolished since.

On June 21, 1549, Andrzej Kościelecki, Bydgoszcz starosta and governor of Poznań, came to terms with the City Council to have public baths built.

In 1573, the governor and mayor of Bydgoszcz, Jan Kościelecki, asked the City Council to renovate the devastated public baths, for hygienic purposes.

[4] On a detailed plan of the city, prepared by the Prussian geometer Gretha in 1774, plots along the street are partially occupied by current buildings.

On the map of Lindner from 1800 are clearly visible the new buildings erected during 25 years: the municipal granaries on the river waterfront and the fish Market, established along a dirt road meandering around the ruins of the castle.

[8] In the early 20th century, on the site of the former castle was built an evangelical temple, which after World War II became the Jesuit's church of St. Andrew Bobola.

[2] In 1940, on Hitler's orders, the Nazi occupation authorities demolished buildings and granaries nearby Mostowa street (in particular houses Jachmann and Fryderyk).

[12] In December 1939, when Nazi forces took the city, collections were moved to the Municipal Museum building on Mill Island, leaving the edifice at the care of curator Kazimierz Borucki.

[9] In 1964, the eastern part has been rebuilt and in 1989, a monument to Leon Barciszewski (Bydgosdzcz Mayor) has been unveiled in the nearby square – it has been moved to Długa street in 2008.

[16] Building at 12 Eclecticism First quarter of the 19th century[15] This tenement housed a German restaurant "Alt Bromberg", called then "Stara Bydgoszcz" during interwar period.

[18] For this purpose, the edifice at Nr.12 has been thoroughly restored[19] Bydgoszcz Chamber theatre at 14/16 Registered on Kuyavian-Pomeranian Voivodeship Heritage List, Nr.601341, Reg.A/887 (June 21, 1993).

[11] The chamber theatre, built in 1875–1876[15] and rebuilt in 1897 by Karl Bergner in the style of Eclecticism,[20] has initially housed a restaurant with a bowling alley and a garden, one of the several dining and entertainment complexes operating in Bromberg at this time.

[21] After 1956 Gomułka's thaw, the Polish Theatre in Adam Mickiewicz Alley turned to more spontaneous performances and began to look for other premises: attention was then drawn to an abandoned building at Grodzka Street 14–16, and a second theater scene started there.

Its program included plays from Jan Potocki, Henry Becque, Keith Waterhouse, Oscar Wilde, Jerzy Jurandot, Alfred Hennequin and many more.

[21] Chamber theatre scene was the place for experiments of new, high-profile and avant-garde plays adapting literary Polish and foreign works.

The new theatre features, among others, a multifunction amphitheatre with 187 seats, workshop and meetings rooms, so as to support artistic and social development.

In the 19th century, it was a central place for business, and in neighboring granaries were stored fish and herring transiting from Gdańsk using Brda waterway.

He was the co-founder with Heinrich Dietz, in 1873, of one of the major shipping companies in East-Prussia, Lloyd, with local branch in Königsberg, Elbing and Dantzig.

Later, when the property was sold to Inland Waterways shipping company "Bromberger Schleppschifffahrt Aktien Gesellschaft",[24] a reconstruction of the building was carried out to fit it for administration and office purposes.

The property was sold in 1995 to BRE Bank, which realized a thorough renovation of the palace, with reconstruction of architectural details (cornices, pediments, pinnacles, obelisks, spire with weather vane).

At the very place of the old ancillary facilities, BRE Bank has ordered in 1997–1998 to architect Andrzej Bulanda two modern glass-steel-and-clinker-brick buildings, known as "new granaries".

[26] A special tribute to the school was put by foundation funds established on June 4, 1869, by a Bydgoszcz mayor, Karl von foller.

At the beginning of the 19th century, on the plot of today's square were erected cane sugar refineries, partly re-using material from the ruins of the nearby castle.

The administrative building (the only one preserved) was sold in 1855 to city counselor Knopf, who rented it to tenants, hence the four different entries that still exists, associated with various postal addresses.

In 1977, PZU (National Insurance) Group bought it and rebuilt it in 1981 to the current outshape, mending the repeated devastations undergone so far.

In the square located between the PZU building and Bernardyński bridge on the east stands the Jubilee oak: this tree has been planted on April 23, 1997, to celebrate the 650th anniversary of the creation of Bydgoszcz city.
