[7] The four graves contain the remains of Slovene, Croatian, and German civilians that were murdered on the Gorica Ridge northeast of the town in late May 1945 as they were fleeing to Carinthia.

The Janez Pirmanšek Grave (Grob Janeza Pirmanška) lies in a meadow west of the town, at Primorska Cesta no.

A memorial to Šoštanj residents that fell while serving in the German army formerly stood at the site.

[12] There are currently five units in the TEŠ (Termoelektrarna Šoštanj) power plant, which is owned by Holding Slovenske Elektrarne (HSE).

There are claims by the Slovenian media that there is evidence of corruption in the project regarding the involvement of Alstom, the main equipment contractor.

Ten people were charged with destruction of business documentation and abuse of office and forgery; Alstom is said to have changed certain terms of its contract, thus causing the project's costs to increase.

For a number of years, the plant could be responsible for 70 to 80 million euros in losses; considering the amount of loans towards the EIB, taxpayers in Slovenia would have to pay more money to support this project.

[18] Slovenian prosecutors filed charges of corruption and money laundering against two individuals and Alstom in 2020 in connection with TES 6.

[19][18][20] The parish church in the town is dedicated to Michael the Archangel and belongs to the Roman Catholic Diocese of Celje.

A second church in town was built in 1776 on the site of a 13th-century predecessor and is dedicated to Saints Hermagoras and Fortunatus.
