Originally the market square consisted of more structures that were crucial to the economy and political life of the city and thus created a microcosm of the city. The Kraków Town Hall existed since the medieval era and was destroyed in the 19th century. Also standing next to the Cloth Hall was the Great Weigh House and the Small Weigh House, which both existed until the 19th century. The foundations of the weigh houses were excavated in the early 21st century and incorporated into an underground museum.
