Aracena Castle was erected in the 13th century, during the Islamic period, and was itself built on the site of an ancient Moorish castle. The walled enclosure was partitioned inside, with the tower of homage, or castle keep, defending the barrier that divided its interior. The population of Aracena settled around this structure, giving rise to the current urban landscape. During the late Middle and Modern Ages, Aracena continued growing from the Cerro del Castillo (castle hill) into the valley, first as unattached land dependent on Seville and later, in the seventeenth century, as a feudal estate under the jurisdiction of the Count-Duke of Olivares. Still later, it was under the Count of Altamira, who carried the title of Prince of Aracena.
The fortress consists of the alcazaba, or citadel, with its watch tower, cistern and walls; these are flanked by other towers, as well as a fence line that, in its interior, once accommodated medieval living quarters.
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.
