Peter Kosler

Kosler was born in Koče,[1] a village south of Kočevje in Gottschee County, in what was then the Austrian Kingdom of Illyria, and is now Slovenia.

Born in a relatively well-to-do family, Kosler made a fortune with beer brewing and was the founder of the Union Brewery.

The Koslers also owned a mansion (Slovene: Kozlerjeva palača) in the center of Ljubljana, close to Congress Square (Kongresni trg) and Čop Street (Čopova ulica), which was regarded as one of the finest Baroque buildings in the city.

According to an interview with art historian Damjan Prelovšek in October 2006, trees now grow at the site of the former building, demonstrating that its demolition was a political decision and unnecessary in order to widen the street.

During World War II, the plot was used as a mass grave for victims of the Slovenian Home Guard torturer and killer Franc Frakelj.
