The tuff massif above Hontianske Moravce conceals a system of 42 underground rooms inside, which makes it unique in Slovakia.

"The conditions for storing wine in tuff rock are unique thanks to the year-round stable temperature. It is the best natural climate for wine and its perfect maturation," says Peter Nagy, one of the owners of the wine cellar.
Nagy comes from the Nitra Region, buying the cellar five years ago. He adds that today the original place is also used for wine tasting and recreational purposes.
