The Salvador church was erected on the remains of the Ibn Adabba, the Great Mosque of Muslim Seville (9th century). This religious temple, as well as its surroundings, had great importance in the daily life of the people, which is why when the Christians conquered Seville, they allowed it to be used as a mosque in the beginning, but in 1340, it was converted into the parish of Salvador.
In addition, it was agreed to maintain the ostentatious rank of the second temple of the city; for it was granted a collegiate character. Thus, this building would continue to be used religiously until 1671, when the passage of time left it strongly deteriorated. Its construction as we see it today began in 1674 with the architect Esteban García. Work ended in 1712 under the architect Leonardo de Figueroa.
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.
