Due to the so-called Shortly before World War II, the Czechoslovak Socialist Republic had to cede to Hungary the territory of southern Slovakia. As a result, some railway lines were interrupted and the need arose to build new ones. However, when Hungary returned the occupied territories after the war, the completion of new lines became pointless and many unused monuments remained after the construction work began. These monuments include the Slavošovský tunnel under the Homôľka hill, which connects the villages of Slavošovce and Magnezitovce (part of Kopráš).
The tunnel, through which no train has ever passed (there are not even rails), is a popular tourist attraction today. Even foreign visitors are looking for it. Its length is about 2.5 km and can be crossed in less than an hour. Moisture, cold and dark black darkness await the visitors of the tunnel, which in combination with the fact that one never knows what one will encounter in an unlit underground, creates an unforgettable adrenaline experience.
Waterproof shoes, warm clothing and your own light source must be taken to cross the tunnel. The route can also be completed by bicycle. In front of the entrance to the tunnel on the Slavošovská side, there is a pleasant recreation area with gazebos, a fireplace and swings.
