Tristen Arboretum

Brief information

The Trsteno Arboretum grew out of the Gozze family’s request to ship captains: to bring back seeds and plants from their voyages. That is why it is not just an old seaside park, but a place where sea routes quite literally entered the garden layout. The source calls it Croatia’s oldest botanical garden and the only arboretum on the Croatian Adriatic coast.

By 1492 the garden already existed: that year, an aqueduct with a 15-meter span was built to irrigate it, and it has survived. Different periods came together inside the arboretum: the park around a 15th-century summer residence, Croatia’s oldest Renaissance park with exotic plants, and the 19th-century park in Drvarica. Here, history is read not from plaques, but from the way water, house, and plants became linked in a single system.

What to notice first

It is worth noticing three key details. The aqueduct matters not as a separate old structure, but as an explanation of how the arboretum works: rare plants here required constant irrigation, so from the very beginning the garden depended on engineering. The 15th-century summer residence shows another layer of the idea: the park arose beside the country house of a noble family, not as a modern public green space. The 19th-century park in Drvarica adds a later section, which can be mentally compared with the Renaissance core.

The most vivid living detail is the two Oriental plane trees on Trsteno’s central square. They are more than 500 years old; one reaches about 45 meters, the other around 60, and their trunks are about 5 meters in diameter. They survived the wartime fire of 1991 and the forest fire of 2000, so their scale also reads as a trace of the arboretum’s survival.
