Stari Grad Plain on the Adriatic island of Hvar is a cultural landscape that has remained practically intact since it was first colonized by Ionian Greeks from Paros in the 4th century BC. The original agricultural activity of this fertile plain, mainly centring on grapes and olives, has been maintained since Greek times to the present. The site is also a natural reserve. The landscape features ancient stone walls and trims, or small stone shelters, and bears testimony to the ancient geometrical system of land division used by the ancient Greeks, the chora which has remained virtually intact over 24 centuries.Stari Grad Plain represents a comprehensive system of land use and agricultural colonisation by the Greeks, in the 4th century BC. Its land organisation system, based on geometrical parcels with dry stone wall boundaries (chora), is exemplary. This system was completed from the very first by a rainwater recovery system involving the use of tanks and gutters. This testimony is of Outstanding Universal Value.The land parcel system set up by the Greek colonisers has been respected over later periods. Agricultural activity in the chora has been uninterrupted for 24 centuries up to the present day, and is mainly based on grapes and olives.
