Piekarnia Mamut, Historic bakery in Śródmieście district, Wrocław, Poland.

Piekarnia Mamut is a complex of former bakery buildings at ul. Sienkiewicza in the Śródmieście district of central Wrocław. The structure was built as a bakery warehouse for the Breslauer Consum Verein and was expanded in 1928 when bread-baking technology changed. It is no longer a working bakery.

The building was erected as a bakery warehouse for the Breslauer Consum Verein. It was expanded in 1928 due to a change in bread-baking technology. It was among the largest such facilities in Germany, and in 1945 it baked 8 tonnes of baked goods per day. After World War II, PSS Społem took over the building.

The complex is a former bakery, not an active one; its name, Mamut, refers to the scale of production. The site belonged to the Breslauer Consum Verein and later to PSS Społem, the Polish consumer cooperative, which took over the building after World War II.

The complex stands at ul. Sienkiewicza in the Śródmieście district of central Wrocław, a short walk from the main railway station and served by trams and buses along the surrounding streets. It is a former production site rather than a working shop, so visitors view the buildings from the street; the gate and yard are best seen on weekdays.

The 150-tonne daily output was reached after World War II under PSS Społem; in 1945 the site baked 8 tonnes a day. The building began as a warehouse for the Breslauer Consum Verein and was extended in 1928 when bread-baking technology changed.
