Pilsen's historic underground system consists of a complex system of corridors, two- to three-story cellars, and hundreds of wells under the historic city center. It was built under the city from the end of the 13th to the 18th century. With its thirteen kilometers of corridors, it is one of the largest historic underground systems in Central Europe. The visitor tour is operated today by Plzeňský Prazdroj, with access at the Pilsen Brewery Museum. The almost 800-meter-long tour begins in the "cooler," from which meltwater flowed into the cellars and cooled them. Food was stored in the cellars, and beer was fermented and matured. During wars, the underground served as a refuge for the people of Pilsen, and its corridors enabled communication. In addition to the labyrinth of corridors and cellars with numerous wells and cisterns, the tour also includes a historic 16th-century waterworks on the park wall with a replica of a water wheel.

Very unusual and worth seeing rock formation. The path there is also a lot of fun, a great narrow trail over roots and rocks.

Relatively inconspicuous, you could easily drive right past it...

Uranium was once mined in this tunnel, but it was not profitable.

Here, a clearing in the forest was used to create a small "sacred area" in the middle of nature, one that cyclists shouldn't pass by unnoticed. A small hill constructed of natural stone—one could also call it a grotto—rises in the middle of the forest clearing. It is crowned by a cross with the Corpus Christi. The centerpiece of this small sacred monument, however, is a depiction of the Virgin Mary, with a votive tablet on either side of her image. Seating and tables complete the ensemble.

Beneath the center of Pilsen lies a labyrinth of cellars and passageways dating back to the 13th century, nearly 13 kilometers long. The entrance is at the Beer Museum/Brewery Museum. In these cellars, beer (with ice!) and other foodstuffs were stored. These were connected (one level below!), springs and streams were incorporated, and thus this invisible network of passageways beneath the city was created.
