1954 · 1972 A cave found by accidentJaskyňa objavená náhodou

In 1954 workers of the East Slovak ore survey, based at Jelšava, were driving a prospecting adit called Kapusta into the Hrádok hill a few kilometres from the village, looking for iron ore. Martin Cangár and Jiří Prošek broke into a cavity instead — and what was growing in it was not dripstone. The chambers held aragonite, a mineral chemically identical to ordinary calcite but crystallising differently: it grows outwards in white needles and clusters, like frost on a window, instead of dripping down into columns. The cave was opened to visitors in 1972, with a route of about 230 metres, and it stays at a steady seven degrees all year.V roku 1954 razili pracovníci Východoslovenského rudného prieskumu so sídlom v Jelšave prieskumnú štôlňu Kapusta do kopca Hrádok pár kilometrov od dediny — hľadali železnú rudu. Martin Cangár a Jiří Prošek namiesto nej narazili na dutinu a to, čo v nej rástlo, neboli kvaple. V priestoroch bol aragonit, nerast chemicky totožný s bežným kalcitom, ktorý však kryštalizuje inak: rozrastá sa do bielych ihlíc a trsov ako mráz na okne, namiesto toho aby stekal do stĺpov. Jaskyňu sprístupnili verejnosti v roku 1972 s trasou dlhou približne 230 metrov a po celý rok v nej býva stálych sedem stupňov.
