It belongs to the mining settlements in Gemer region. It probably got its name from the “salt road” that led from the Polish cities of Bochnie and Wieliczka already during the time of the Great Moravian Empire. In addition to iron ore, precious metals, mainly silver, pure mercury and cinnabar, have been mined in the village. In 1241, our territory was plundered by the Tatars, who crossed entire Slanská valley and devastated everything they could. After the withdrawal of the Tatars, the Hungarian rulers called to us German miners who had already mastered underground mining. The village of Nižná Slaná has been granted the privileges of a free mining city since the Middle Ages. This privilege was granted to the village in 1417 by king Sigismund. Silver, copper and mercury-containing ores and later mainly iron ores, were mined in the village and its surroundings. Siderite iron ore mining and production was stopped here in 2008. Currently, the area of the former plant is dilapidated and is gradually and arbitrarily dismantled.
