Before Wrocław became a city of factories, it was a city of guilds: butchers, blacksmiths, potters and bakers organised into associations that watched over the quality of goods and defended their monopoly over their craft. Traces of this medieval order can still be seen in the city's topography, and successive layers - mills on the Oder, 19th-century factories, breweries and large industrial plants - built up on top of one another over the following centuries, right up to today's post-industrial buildings, which now serve entirely different purposes.

Craft guilds and their traces in the city

The oldest evidence of organised craft in Wrocław is Stare Jatki (Old Butchers' Street), which served as a butchers' trading quarter from 1242 - two rows there held twenty-four meat stalls each. The butcher's trade survived here for centuries: as late as 1939 two meat stalls were still operating here, though only that many remained of the original forty-eight. Today the restored stalls house craft galleries, and at the entrance from Odrzańska Street stand sculptures of animals - a goose, a goat, a pig and a calf, put up in 1997 as a monument to slaughtered animals, later joined by a duck, a cockerel and a rabbit.

Wrocław's municipal economy goes back even further: a mint operated in the city from the first half of the 11th century, making it one of the oldest forms of organised production in this part of Europe. As in other medieval towns, individual crafts clustered around specific streets, which can still be read today in the city's street names - the name Stare Jatki refers directly to the old meat trade, and the arrangement of workshops around the Market Square and the city's oldest streets reflected the division into guilds, each of which watched over its own slice of the city's trade and craft.

Mills on the Oder

From the Middle Ages the Oder powered the city's economy quite literally - with mill wheels. In 1334 the Kraków merchant Mikołaj Wierzynek signed an agreement with Wrocław's town council financing the construction of mills, in exchange for a share in the profits from their operation. The first two 14th-century mills stood on the site of today's southern hydroelectric plant, at the outlet of Kiełbaśnicza Street. Over time, five mills operated on Kępa Młyńska and the neighbouring islets: Przedni, Średni, Nowy, Na Kępie and Pomorski, alongside fulling mills and malt houses. From the 16th century to the early 20th century, the whole system of Wrocław's canals and weirs kept between forty-five and sixty mill wheels running on average, driving various industrial devices - a scale that shows how long the river remained the main source of energy for the city's crafts and industry.

The era of water mills ended in the 1920s. The last of the five mills was finally closed down then, and in their place a lower water barrage was built on the Oder together with two hydroelectric plants. These plants still operate today as historic pieces of the city's water infrastructure - standing on the very spot where, for six hundred years, mill wheels ground grain for Wrocław.

Large-scale 19th-century industry

Industrialisation changed the scale of Wrocław's economy from craft-based to factory-based. One of the best-documented examples is the plant that started out in 1832 as Maschinenbauanstalt Breslau, and from 1839 operated as Wagenbauanstalt Gottfried Linke - one of the oldest European manufacturers of railway carriages. The company, later known as Linke-Hofmann-Werke, produced railway and tram rolling stock, including the city's first tram with a steel body, the LH Standard type, and during the First World War it also manufactured aircraft. This shows how flexibly the large Wrocław plants adapted their production to the needs of their era, from peacetime rolling stock to wartime equipment.

Municipal infrastructure grew at a similar pace to private industry. In 1904-1905 the Municipal Gasworks was built in Wrocław, and in the same period, in 1904-1906, the water tower on Aleja Wiśniowa was built in the Borek district, designed by Karl Klimm as part of the municipal water supply network. The tower is sixty-two metres tall, and at a height of forty-two metres it held an observation gallery, from which, in good weather, one could see Mount Ślęża thirty kilometres away, and even the Karkonosze (Giant Mountains) a hundred kilometres further on. From 1908 the tower's staff would raise a red flag at its top on days of good visibility, and a fee was charged for the lift ride up to the gallery - one of the few examples of municipal technical infrastructure that was also a tourist attraction from the moment it was built.

Brewing

Brewing was an industry large enough in Wrocław that several separate breweries operated in the city at the same time. Browar Piastowski (Piast Brewery) in Ołbin, known before the war as Brauerei Pfeifferhof Carl Scholz, had its beginnings in the early 19th century on Świdnicka Street. In 1831 it was bought by Ernst Wilhelm Eduard Scholz, and in 1893 his successor Carl Scholz bought land to build a new, larger plant, fitted with a cooling unit made by Linde, advanced for its time, and water treatment equipment. In 1910 the brewery was bought by the Schultheiss concern.

The second large Wrocław brewery, known today as Browar Mieszczański (Burghers' Brewery), was founded in 1894, when Robert Hain, the owner of the Alter Weinstock inn, built his own beer production on Hubska Street for the needs of his establishment. In 1907 the plant was bought by the Association of Wrocław Innkeepers and Tavern Owners, which turned it into a much larger enterprise under the name Bürgerliches Brauhaus Breslau, producing at the outset around six thousand hectolitres of beer a year - a figure that kept growing even during the Second World War.

The fate of the plants after 1945

The war and the change of borders in 1945 broke the continuity of ownership of most of Wrocław's plants, but did not always halt production itself. The Linke-Hofmann-Werke wagon factory, where around five thousand forced labourers worked during the war producing, among other things, rocket propulsion for V-2 missiles, passed in July 1945 under Polish state administration and was renamed Państwowa Fabryka Wagonów (State Wagon Factory) - Pafawag. In the 1950s Pafawag became Poland's largest producer of electric locomotives, and by the 1990s it had produced more than one thousand four hundred electric locomotives and one thousand six hundred electric multiple units. The plant later changed owners - from Adtranz, through Bombardier Transportation, to today's Alstom Polska - but has continuously produced rolling stock to this day, making it a rare example of a Wrocław industrial plant with an unbroken continuity going back to the 19th century.

The breweries were less fortunate. Browar Piastowski, nationalised in June 1945, resumed production already in October of the same year under a new name, but ultimately ceased operating in 2004, when the Carlsberg group closed it down. Browar Mieszczański, destroyed in 1945, was rebuilt in the 1950s, and from 1965 produced on average one hundred thousand hectolitres of beer a year, mainly pale and full-bodied beers - production finally ended in 1996.

Post-industrial buildings in new roles

The sites of former industrial plants have found a second life in Wrocław, though usually in a role quite different from their original one. Browar Mieszczański on Hubska Street, after production closed in 1996, was rebuilt and since 2003 has operated as a cultural centre with theatres, galleries, workshops and exhibition spaces covering twelve and a half thousand square metres. The site of Browar Piastowski in Ołbin has been under redevelopment by a developer since 2017 into a mixed residential and service estate, while keeping its status as a listed heritage building. The water tower on Aleja Wiśniowa, after decades without maintenance from the end of the war to the 1990s, is now closed to visitors, but still stands as a landmark of the Borek district, awaiting the next stage of its history.

The same logic - keep the structure and detail, change the function - applies to most of Wrocław's post-industrial buildings that have survived to this day. Factories producing rolling stock still work under new names, but breweries and water towers have become spaces for culture, housing and offices - this is the most visible way in which the city's old crafts and industry still shape its architecture today. The history of the great industrialists and factory owners of the whole region, who stood behind similar plants outside Wrocław, is described in a separate article on the portal.
