The article describes the brief period of Josip Gorup von Slavinjski's life in Trieste. During the course of seventeen years, Gorup had accumulated a considerablefortune, which has not been forgotten to this day. Gorup was a nationally-minded Slovene. He extended substantial financial contributions to Slovenian cultural institutions, not only in Ljubljana, his native village of Slavina and Inner Carniola, but also - and above all - in Gorizia and Trieste. He supported cultural, political, and commercial associations, even Južni Sokol, the only Trieste-based sport society, which was established on 6 May 1869 and later renamed Tržaški Sokol. Mention should also be made of Gorup’s sponsorship of the artist Ivan Rendic, who later built a family tomb for him in Rijeka.
