Podziemna Trasa Turystyczna w Sandomierzu

Beneath Sandomierz's Market Square runs a route through 34 linked chambers lying 4 to 12 metres underground. They are merchants' cellars and storerooms from the 14th and 15th centuries, uncovered and stabilised after ground collapses in the 1960s. You enter at Rynek 10 and come out in the town hall. The route has been open to visitors since 1977.
