Lopera Castle is a big castle in the city center made up of irregular masonry. It has an irregular pentagonal base. The castle is defended by five towers, some of the towers are cylindrical and some others are prismatic. It has machicolated balconies, a defensive device to better guard entrances and some of the fortified towers.
There were Romans and Visigoth settlements until Lopera was conquered by the Muslims at the beginning of the 8th century. During the 9th and 10th centuries, the population moved to the current town where a small Muslim farmstead was created. During the 11th century, the farmstead was fortified as a defence against Castilian attacks.
Once Lopera was conquered by the Christians, King Ferdinand III relinquished it to the Order of Calatrava. The Order of Calatrava built the castle that exists today. This castle guaranteed an escape to river Guadalquivir.
In 1856, the castle was acquired by Alonso Valenzuela who turned it into public property.
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.
