The Small Weigh House (Polish: Mała Waga Miejska) is a former structure that existed on the main square of Kraków, Poland.
It was a public building in which smaller goods such as soap and resin were weighed.
During the Renaissance, the building was rebuilt probably by Gasparo Arcani de Mesco, who crowned the attic in the Renaissance style, with coats of arms of the king and the characters Samson, Darius, Xerxes and Scipio.
However the importance of the weigh houses diminished and it was probably demolished in first half of the 19th century.
The foundations of the weigh houses were excavated in the early 21st century and incorporated into an underground museum.
