From the 17th century, Horní Jiřetín, divided by the stream Jiřetínský potok, was mainly governed by the Lobkowicz and Waldstein families.

## Economy

In the past, the inhabitants of Jiřetín subsisted mainly on fishing in Lake Komořany, ore mining and various forms of agriculture, mainly arboriculture. Lignite has been continuously mined in Horní Jiřetín since the middle of the 19th century. Today, a significant part of the municipal territory is occupied by a lignite surface mine, Lom ČSA. In 2015, the Ministry of Industry proposed breaking the mining limits imposed on the mine. This would lead to the demolition of 170 houses in Horní Jiřetín. However, the proposal specifically for this mine was not accepted.
In 1828, a cotton plant was built in Mariánské Údolí. It is still in operation today as the Triola company and it manufactures underwear and swimwear.

## Transport

The I/27 road (the section from Most to Litvínov) runs along the eastern municipal border.

## Sights

The most important architectural monument is the Jezeří Castle incorporated into the slopes of the Ore Mountains. It was originally a Gothic castle from the 14th century, later rebuilt in the Renaissance and then in the Baroque style. Most of its English-style park was destroyed by coal mining. Since 2023, it has been protected as a national cultural monument.
In Horní Jiřetín is the valuable Church of the Assumption of the Virgin Mary. It was built in the early Baroque style in 1694–1700 according to design of the architect Jean Baptiste Mathey.
