Piazza Armerina Cathedral is dedicated to Mary of the Victories (Maria Santissima delle Vittorie). It is the seat of the Bishops of Piazza Armerina.
Built on the foundations of an earlier church of the 15th century and based on a design by architect Orazio Torriani, its construction began in 1604 and ended in 1719, while the dome was added in 1768. It became the seat of the Diocese of Piazza (later Piazza Armerina) when it was created in 1817.
The interior of the cathedral is dominated by the central dome. It contains a cross painted on both sides, showing the crucifixion and resurrection of Christ, and a baptistery by Antonello Gagini.
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.
