Gemer region is situated in Slovenské rudohorie approximately between the present-day Slovak-Hungarian border, the towns Poltár and Rožňava and the Low Tatras (Nízke Tatry).
The territory approximately between the towns Tiszolc and Rimaszombat, called Kis-Hont was merged with Gemer from 1786 until 1790, and again in 1802.
This situation lasted until the end of the war, when First Vienna Award was reverted and 92.5% of the area became part of Czechoslovakia again.
Evidence of the region's past wealth is the number of mansions and palaces, and many preserved medieval churches with quality frescoes.
Thanks to the wealth from mines, most villages in Gömör could already in Middle Ages afford to have their own stone church.
Big credit on development of mining in Gömör in Late modern period had noble family Andrássy, notably count Manó Andrássy, who had built several ore mills, thanks to what he was called "Iron Count".
Gradually most of the mines and plants in the region were taken over by Rimamurány-Salgótarjáni Vasmű Részvénytársaság (Rimamurán-Salgotarján Ironworks Company).
In addition, mining companies, which had been already declining before the disintegration of Hungarian Kingdom suddenly gained new rivals from Bohemia.
Modern employers in the region include Slovenské Magnezitové Závody Jelšava and SLOVMAG Lubeník, which mine magnetite, paper mills SHP Slavošovce and producer of mineral water Gemerka.
[citation needed] Historically, Gömör is associated with three ethnic groups: Hungarians, Germans and Slovaks.
As part of settlement policies, many settlers from Germany came to work in mines in the Middle Ages.
On the south, notably amongst Hungarian population prevails Calvinism of Reformed Christian Church.
Despite its current poverty, because of its former wealth, Gömör has an interesting history, many historical monuments and authentic wild nature.
In 2020, most valuable frescoes in 12 medieval churches in Gemer had been nominated for European Heritage Label.
These include iron-mills in Nižná Slaná (Huta Etelka) and in Vlachovo (Huta Karol), a never finished system of freely accessible railway tunnels and bridge in Slavošovce and in Manezitovce known as Gemerské spojky.
A tourist destination, especially in spring, is the village Brdárka known for its cherry orchards and Baroque church.
