The origins of the present Chelva town can be found in the 11th century, when the ruling Moors established a fortress. The original city center was developed adjacent to the castle. It was enclosed by a wall with four gates (one is still visible, San Cristobal). Because of these fortifications, Chelva was a town of considerable importance during the Muslim rule.
The castle was converted as a palace where the Viscount of Chelva stayed from the late 14th century. The building evolved architecturally, eventually presiding over the Main Plaza. An Iberian occupation from the 4th century B.C. has recently been discovered, and the location of Chelva’s first Christian church within the castle walls from the 13th century has been confirmed.
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.
