The Cathedral of Monreale is one of the greatest existent examples of Norman architecture. The construction of Monreale, started in 1172, was approved by Pope Alexander III with a bull on 30 December 1174. Works, including an annexed abbey, were completed only in 1267 and the church consecrated at the presence of Pope Clement IV. In 1178 Pope Lucius III established the archdiocese of Monreale and the abbey church was elevated to the rank of cathedral. The archbishops obtained by the kings of Sicily a wide array of privileges and lands in the whole Italian peninsula. In 1270 Louis IX, King of France, brother of King Charles I of Naples, was buried here.
In 1547-1569 a portico was added to the northern side, designed by Giovanni Domenico Gagini and Fazio Gagini, in Renaissance style, covered by a cross vault and featuring eleven round arches supported by Corinthian columns. In 1559 most of the internal pavement was added.
The church's plan is a mixture of Eastern Rite and Roman Catholic arrangement. The nave is like an Italian basilica, while the large triple-apsed choir is similar to one of the early three-apsed churches, of which so many examples still exist in Syria and elsewhere in the Middle East. It is like two quite different churches put together endwise.
The main internal features are the vast (6,500 m2) glass mosaics, executed in Byzantine style between the late 12th and the mid-13th centuries by both local and Venetians masters.
Since 2015 it is part of the Arab-Norman Palermo and the Cathedral Churches of Cefalù and Monreale UNESCO Heritage site. The church is a national monument of Italy and one of the most important attractions of Sicily.

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.
