Supersam
supermarket in Warsaw, Poland
Supersam (also stylilised as SuperSam and Super Sam) was a modernist supermarket in Warsaw, at Mokotowski Square, built in 1962 and designed by Jerzy Hryniewiecki, Maciej Krasinski and Ewa Krasińska with structural engineer Wacław Zalewski. It was the first self-serve supermarket in the country, and was considered a primary example of modernist architecture in Poland. Supersam was demolished in 2006 and replaced by a new architectural complex built between 2013 and 2015.
History
The Warsaw supermarket was built in 1962 at the Lublin Union Square (formerly also Mokotowski square,) on the site of the former Polish Radio building. Historically (1770–1818), this place was called Rondo Mokotowskie and standing here was the Southern Gate to the city. The supermarket building was an innovative design with a roof on the principle of tensegrity suspended and kept in place by steel girders and cables, designed by three architects: Professor Jerzy Hryniewiecki, Maciej Krasinski, Maciej Gintowt and three engineers: Waclaw Zalewski, a professor emeritus of MIT, Professor Stanislaw Kusia and Andrzej Żórawski.
Although a campaign was carried out to save the building from destruction as an architectural monument valuable PRL and unique construction design for its time, Supersam was demolished in December 2006.
Architecture and technology
A hanging roof was desired from the beginning, but this would require sloping roof mainstays that would take up valuable real estate and would make the building structure vulnerable to catastrophic failure due to accidents or vandalism. Through progressive designs, a method was developed, by structural engineer Wacław Zalewski, employing the principle of tensegrity, to eliminate the backstays by alternating cables and arches of similar curvature. The outward thrust of arches at their highest points exactly balances the inward pull of the cables at each end.
This brief starts where responsible research should: with the source description of “Supersam” as supermarket in Warsaw, Poland. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as supermarket in Warsaw, Poland. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Jun 14, 2026. The linked authority identifier is Q9348312. Authority coordinates are 52.213, 21.020. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1962, 2006, 2013 and 2015.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
