The Great Weigh House (Polish: Wielka Waga Miejska) was a prominent building that existed on the main square of Kraków, Poland.

It was located in between the Cloth Hall (Sukiennice) and Church of St. Adalbert to the east.

[1] Wielka Waga was a public building in which trading goods transported to Kraków were weighed.

As the official, public control of the weight of goods was crucial, it was run by the local authorities who would use the weights for the levying of taxes on goods sold within the city and transported further.

[1] The foundations of the weigh houses were excavated in the early 21st century and incorporated into an underground museum.
