A hill called Zlatý kůň (Golden Horse) rises above the village of Koněprusy close to another hill called Kobyla (Mare), and nearby is a place called V koníku (In a Little Horse).
Golden Horse hill conceals the most extensive cave system in Bohemia, accidentally discovered after an explosion in a nearby limestone quarry in 1950 and subsequently were made accessible for the public in 1959 [REF].
