The history of the tenement houses at Stary Rynek 73 and 74, dates back to the 15th century.
Over the centuries, their owners represented various nationalities, professions and confessions. Among them we encounter: Poles, Germans, Jews, Hungarians, Italians and Greeks; they were magnates, internationally renowned merchants, tailors, town patricians, furriers and wine merchants.
The place was inhabited by Catholics, Protestants, Jews and Orthodox.

The tenement houses became a silent witness of some unusual events:

• a contingent of the Brandenburg soldiers was based in one of them during the Great Northern War,
• in the 18th century the Greeks arranged here an Eastern Orthodox chapel,
• during the annexation period it functioned as the seat of the Polish Singing Group cultivating Polish song,
• for many years Tailor’s Guild was operating there.

The greatest historical discovery is the fact that in the 17th century both tenement houses were for some years owned by brewers. One of them belonged to the brewer family of Stanisław Krakowianin whereas the second one, brought as a dowry by Magdalena Łukowska (born Sztamet), was owned by the brewer Maciej Łukowski. Thus, there is a high probability that the brewery was located in the yard, which was the custom at that time.

In 1908 the tenement houses were pulled down and replaced with a seat of Industrial Bank, designed by the famous Poznań architect Roger Sławski. The two buildings were destroyed in winter 1945, during intense fights for Poznań liberation. It took 10 years to rebuild them with separate facades. However, until now they have been linked by one common façade overlooking Sieroca Street.
Nowadays, it is decorated with a plaque commemorating the Polish Singing Group and murals referring to sewing traditions.

In May 2004 Brovaria invited its guests to cross the threshold of those beautiful tenement houses, where modern comfort and elegancy of the interior design was skillfully combined with respect for historic details.
