Prehistoric settlement
Judging by the dating of finds from the graves on the neighbouring islet of Mali Vinik, the settlement on Gradina certainly existed from the 11th century BC and lasted until its transformation into a small Roman town.
The prehistoric settlement was elliptical in shape and surrounded by walls enclosing an area of about 150 × 200 m, while the entire area around the fortified part is estimated at 10 ha. It is therefore assumed that this was one of the largest settlements in southern Liburnia.
