Segorbe Castle was an Arabian alcázar (palace or castle). Very little remains of the original alcázar, but the large complex was a residence of lords, dukes and kings for over a millennium.
.After the Muslim king of Valencia, Zayd Abu Zayd, converted to Christianity and declared himself an ally and vassal of King James I of Aragon, he ceded the fortress to James in 1229 and became governor general of Valencia on his behalf. The castle became a sanctuary for Zayd Abu Zayd himself when he was killed by Dynamil Zayyan until James captured the castle in 1245, and placed Abu Zayd in command of an army to assist in the retaking of Valencia.
The castle had a peak in the 14th and 15th centuries, culminating in the holding of General Courts by King Martin of Aragon, who had made the city his residence.
In 1784, urban expansion of Segorbe beyond the original medieval fortifications required further construction, and new walls were built. After the works were completed, the new walls had eight gates.
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.
