Trsteno arboretum by the Adriatic sea covers 255 000 m2.
It’s unknown when the family of Gučetić established the Trsteno arboretum but it existed when they built a aqueduct in 1492. The aqueduct is still in use.
The summer house of the Gučetić family is surrounded by a renaissance park designed 1502.
During the Croatian war of independence 1991-1995 Trsteno was extensively damaged by series of attacks by troups of Serbia and Montenegro. The summer house was partially damaged and completely looted.
Beside the Gučetić family summer house with park the Trsteno arboretum also includes the neoromantic park at Drvarica and in at the Trsteno village market place ther are two magnificent plane-trees (Platanus orientalis). The plane-trees are more than 500 years old.
Trsteno arboretum is since 1950 managed by the Croatian academy of sciences and arts.
