Mělnické podzemí
Fodor's choice
Under the historic center of Mělník lies a secret: a network of underground passages leading to a medieval well. Half-hour guided tours from the Tourist Information Center take you down into the tunnels, which were dug out of the sandstone rock in the 13th and 14th centuries and used as storage rooms, wine cellars, and shelters during times of war. After a short walk, you'll come to the beautiful and unique medieval well. At 184 feet deep and 15 feet wide, it's the largest well in the Czech Republic—yet from above ground in the main square, you wouldn't even know it exists.
