The city's name derives from the Arabic 'qal'at-al-jarar' ('Castle of jars') – a name that attests to the antiquity of the pottery works which are still thriving. It has been inhabited since prehistoric times, as shown by the presence of two necropoleis dating from the second millennium BCE and by numerous other archaeological finds. It was later inhabited by the Sicels pre-Roman population.
The Arabs built a castle here that in 1030 was attacked by Ligurian troops under the Byzantine general George Maniakes, who have left traces of Ligurian language in the current dialect. The city flourished under the Norman and Hohenstaufen domination, becoming a renowned center for production of ceramics.
Caltagirone was almost completely destroyed by the earthquake of 1693. Many public and private buildings have then been reconstructed in earthquake Baroque style. Primarily for this reason the city has been included, together with the surrounding territory, in an area protected by the UNESCO World Heritage program.
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.
