This guide shows the history of the underground and gives tips for visiting.
History of the Sandomierz Underground
Merchant Beginnings
The underground started in the Middle Ages. Sandomierz was an important trading town. Merchants from all over Europe needed safe places to store goods like salt, grain, wine, and cloth. They built cellars under the houses, which later connected into long tunnels.
Shelter in Hard Times
The underground was also a hiding place. During wars and invasions, especially by the Tatars, people hid underground. One legend tells about a brave woman, Halina Krępianka, who trapped invaders there. Stories like this made the underground not just useful but also special.
Forgotten and Rediscovered
For many years, the tunnels were forgotten and fell apart. In the 20th century, people repaired them and opened part of them to tourists. Today, visitors can see about 500 meters of tunnels and learn the town’s story in a unique way.
