[2] Founded in 1960 as Komsomolsk-na-Dnipri, the city was purposely planned and built as the residential and civic area for the Poltava Mining and Extraction Combinat (now controlled by the Ferrexpo) - the most important iron ore-mining company in Ukraine.

There are two gigantic open pit mines and several spoil tips on the city territory, to the north-east and south of the residential area.

However, the passenger service was discontinued and the city relies on intercity and suburban bus links.

On 15 May 2015 President of Ukraine Petro Poroshenko signed a bill into law that started a six months period for the removal of communist monuments and the mandatory renaming of settlements with a name related to Communism.

[3] On 19 May 2016, Verkhovna Rada adopted decision to rename Komsomolsk as Horishni Plavni and conform to the law prohibiting names of Communist origin.
