Cellars in Týn nad Vltavou, Underground structure in Týn nad Vltavou, Czech Republic.

The cellars in Týn nad Vltavou form a network of underground chambers and passages extending beneath the medieval town. These spaces were carved from stone and topped with arched vaults to store large quantities of trade goods.

The oldest passages under the town centre probably date from the 15th century, built while the Čabeličtí ze Soutic family held the Týn estate until 1601. Work on the system ended after the estate changed owners in 1601 or at the start of the Thirty Years' War, when the town lacked money. The purpose is still debated: drainage and cisterns, cellars under narrow plots, or a wartime refuge.

Local legends say the passages run from the square under the Vltava to Malá Strana, or even four kilometres upstream to the Hněvkovice chateau, wide enough for a carriage. In the tale it is a fiery coach, driven by the cruel former lord Jeroným Hozlauer of Hozlau as punishment for killing a servant who helped him hide a treasure.

The cellars are open to visitors through guided tours where guides explain the layout and historical use of the spaces. Wear comfortable shoes since the passages are narrow and the floors can be uneven.
