The first town hall in Rzeszów probably existed in the 14th century. The town foundation act from 1427 issued by Piotr Lunak from Wiśnicz and Stoigniew from Szumsko confirms the existence of the town hall together with cellars at that time, where wine and honey were sold. Further history of the village is unknown, probably during fights with invaders and in city fires it was destroyed many times. The new town hall was built on the order of Mikołaj Spytek Ligęza before 1591. It was a small stone building with a porch, a vestibule and a tower, surrounded by numerous stalls. This building was destroyed during the invasion of Jerzy Rakoczy in 1657. The building of the town hall is mentioned in documents only at the end of the 17th century. 1730 it was renovated and expanded under the leadership of KH Wiedemann. It was a building of various shapes, with a clock tower.
