The arboretum was erected by the local noble family Gucetic - Gozze (see House of Gozze) in the late 15th century, who requested ship captains to bring back seeds and plants from their travels. The exact start date for the arboretum is unknown, but it was already in existence by 1492, when a 15 m span aqueduct to irrigate the arboretum was constructed; this aqueduct is still in use. It has been the property of the Croatian Academy of Sciences and Arts since 1948, when it was donated. The Arboretum reserves a very special place among the old Ragusan, Dalmatian and Mediterranean parks. It includes a park surrounding the fifteenth century summer residence, which is a monument of garden architecture, and a nineteenth century park at Drvarica.
The arboretum passed into Yugoslav state ownership in 1945, and was declared a natural rarity in 1948. Since 1950 it has been managed by the Croatian Academy of Sciences and Arts. In 1962 the Arboretum Trsteno was registered in the list of protected natural monuments list as a monument of landscape architecture. The protected area covers around 255,000 square metres.
Trsteno suffered extensive damage and looting during the Croatian War of Independence when on October 2 and 3rd, 1991, the Yugoslav People's Army launched a series of gunboat and air attacks and set the Arboretum afire, destroying a large part of it, and causing partial damage to the summer residence and the oldest part of the arboretum. The arboretum was further severely damaged in 2000 by a forest fire during a drought, when around 120,000 square metres were lost in fire.
The pride of the arboretum, two Oriental Planes located on the central market place of Trsteno, survived both disasters undamaged. They are over 500 years old and are unique specimens of their kind in Europe. The ancient trees are both about 45/60 m tall and their trunks are 5 m in diameter. Within what was once the noble family's country house, there is the oldest Renaissance park in Croatia, designed in 1502, with numerous exotic plants.
