"Stráž" wine cellars in village Vrbice, Czech Republic were built by digging into ...

... the village’s sandstone hillside in the 18th and 19th centuries. Long corridors stocked with wine can be accessed through the pretty stone entrances, which look like tiny houses, and are decorated with Gothic arches. Many times, multiple levels of cellars were stacked one above the other. The cellars’ walls are covered with a type of mold, which helps create a suitable environment for the wine to mature. The biggest of Vrbice’s cellars, U Jezírka, goes seven stories deep.
