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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
