History

In 1954, when the Free Territory of Trieste was dissolved and Zone B was assigned to Yugoslavia, Gradin (together with Abitanti, Belvedur, Brezovica pri Gradinu, Koromači–Boškini, Močunigi, Pregara, and Sirči) was originally assigned to the Socialist Republic of Croatia. In 1956 these villages were reassigned to the Socialist Republic of Slovenia.
