The area ties in the square outside the walls of the city, just beyond the Poznań Gate, located at today's western tip of Długa street.

[2] From 1838 onwards, the triangular square at the junction of Długa, Poznańska, and Podgórna streets was the venue for trading firewood and wool collected from the surrounding farms which ran sheep breedings at the initiative of the "Economic Society for Kujawy" Polish: „Towarzystwa Ekonomicznego dla Kujaw”.

With import of overseas cotton, sheep breeding gradually declined, and wool trading disappeared: its traditions remained in the name of the square, officialized in 1854.

An overhaul of the area with renovation of the pavement has been carried out in 2008, highlighting its architecture and the statue of pre-war president of Bydgoszcz, Leon Barciszewski.

The commissioner of the tenement at then Wollmarkt 9 was Wilhelm Kopp, an entrepreneur and owner of a thriving dye house at nearby Swiętej Trojcy street 4/6.

Truthful to his art, Józef Święcicki reproduced here the Neo-Baroque features he was fond of, as in other famous realisations across downtown (e.g. Hotel "Pod Orlem", Plac Wolności 1, Theatre square 2).

The facade is covered with architectural details and motifs: bossage, bay windows, balustrades, columns, pilasters, pediments bearing ornamented tympanums, coat of arms and finials on the roof.

The architecture of this house, with simple elements and gable, reflects other contemporary buildings from the 1850s that one can find in downtown Bydgoszcz (Focha street 6, Gdańska 40).

House at 5 Built after 1915[10] Early Modern architecture, elements of Art Nouveau Prior to this 20th-century building, address was Wollmarkt 12: the re-construction occurred under the ownership of Julius Wiśniewski, pastry and flour merchant.

[11] Today, the tenement harbours Bydgoszcz seat of Solidarność onto the square; the facade onto Mill Island accommodates a cafe (Polish: kawiarnia), Płotka Caffe.

The elevation boasts three superb but discreet stained glasses, on its middle part towering the main entrance, on an Art Nouveau style.

Houses at 6/6A 1850[4] Neoclassical architecture At the end of the 19th century, Carl Gundlach ran there a glaziery shop selling porcelain, till the outburst of the First World War.

On the ground floor, two large round top windows with bossage flanks the double entry, enhanced with pilasters, pediments and a wrought iron grillwork door.

Nr.1, left side of current house, has been owned by a baker, Julius Kolander,[14] from the early 1870s till the end of Prussian period of the city (1920).

Today the building accommodates an ice cream shop, Pracownia Lodów Tradycyjnych, and a night club, Stalownia.

In this house lived Augustyn and Roman Träger, who played an important role during the Second World War in obtaining intelligence on the German V-1 and V-2 missiles tested in Pennemünde, on the island of Usedom (Pomerania).

The edifice lost its beautiful eclectic features, in particular two large wrought iron balconies that used to overhang the main entrance, and a grand Neo-Baroque pediment with urns which crowned the facade.

After the end of World War II, communist authorities opposed any intent to celebrate the memory of the pre-war mayor, declining even the naming of a street despite long-term efforts.

[29] Sculptor Sławoj Ostrowski designed the statue, and bronze casting was performed for a symbolic remuneration by a team from the Gdynia Navy Shipyard under the supervision of engineer Bandrowski.

[29] The unveiling of the monument took place on November 11, 1989, Polish National Independence Day and concurrently the 50th anniversary of Leon Barciszewski's murder.

[29] It then stood on the square between the Brda river and 1 Grodzka Street: the ceremony was chaired by Bydgoszcz mayor, Władysław Przybylski, and Leon Barciszewski's daughter, Danuta Barciszewska-Borkowska, after a solemn service at the cathedral led by Bishop Jan Wiktor Nowak.
