The Garagnin-Fanfogna park in Trogir is considered one of the first botanical gardens in Croatia. It was created based on the idea of the well-known Trogir nobleman Ivan Luka Garagnin at the very beginning of the 19th century. The architectural project is largely credited to the Venetian architect Giannantoni Selva. The complex consisted of four architectural parts: the central garden casinetto, the orangery, the northern utility building (gardener's house), and the southern utility building (barchessa). Since Ivan Luka was involved in agriculture and conservation, he brought over 350 plant species to the park and then placed ancient lapidary stones from the family collection, some of which were found during his excavations in Salona. After World War II, the Garagnin-Fanfogna family moved to Italy, and the park became the property of the municipality of Trogir. In 2008, the park was protected as a cultural heritage site, but today it is completely neglected. The paper explains the process from the park's construction to its current state and it also reviews the most recent known renovation proposals and critically assesses them.
