The Sandomierz town hall anchors the market square — a compact Gothic tower from the 14th century topped with a Renaissance attic added in the 16th century, the combination typical of this region's architecture. It is smaller and more human-scaled than the great town halls of Kraków or Poznań, which suits the town.
The town hall is where the underground tourist route begins. The market square around it is ringed by restored Renaissance townhouses and is the natural centre of Sandomierz's social life — particularly lively on weekday mornings when local traders set up stalls.
