On the meadow, in the middle of the village of Gánovce, in the locality called Hrádok, there is a travertine hill protected as the National Natural Monument called Gánovce Travertines. Maybe not many know them even in Slovakia, still it is one of the most important paleontological sites in the world.

In the 1920s, some blastmaster named Koloman Koky found here a Neanderthal brain cast in travertine mining. He knew that he would get some money for this finding, which he himself considered to be the petrified brain of the animal, and hand it over to researchers of the National Museum in Prague.

Also nearby, there is a geyser that sprays thermal water approximately every 30 minutes.
