Hrušovská jaskyňa
The 77th longest cave in the world
Hrušovská Cave (Slovak: Hrušovská jaskyňa) is a Solutional cave protected as a national natural monument in the cadastral area of the village of Hrušov in the Rožňava District of the Košice Region. The subject of protection is a spring cave with sinter decoration, helictites, calcite crystals and outgrowths of sinter crystals. It was discovered by excavation in the deluvial mantle of the slope of the plateau in 1978 at the site of a flood spring approximately 6 m above the level of the permanent karst spring Eveteš by the caver Róbert Boroš. Several hours later, he also walked through it for the first time and partially explored it together with Rožňava caver, Tomáš Lázár.
