The Stari Grad Plain of the town of Stari Grad on the island of Hvar is an agricultural landscape that was set up by the ancient Greek colonists in the 4th century BC, and remains in use. The plain is generally still in its original form. The ancient layout has been preserved by careful maintenance of the stone walls over 24 centuries, along with the stone shelters (known locally as trims), and the water collection system. The same crops, mainly grapes and olives, are still grown in the fields, and the site is also a natural reserve. The site is a valuable example of the ancient Greek system of agriculture.
The plain demonstrates the comprehensive system of agriculture as used by the ancient Greeks. The land was divided into geometrical parcels (chora) bounded by dry stone walls. The system included a rainwater recovery system involving the use of gutters and storage cisterns. The original field layout has been respected by the continuous maintenance of the boundary walls by succeeding generations. Agricultural activity in the chora has been uninterrupted for 24 centuries up to the present day. What we see today is a continuation of the cultural landscape of the original Greek colonists.
The Stari Grad Plain is Croatia's 7th location protected by UNESCO.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
