Porta Nuova is a monumental city gate of Palermo. It represents the entrance of the Cassaro (the main and most ancient street of the city) from Corso Calatafimi (the way to Monreale) and is located beside Palazzo dei Normanni, royal palace of Palermo.
According to the historian Tommaso Fazello the original gate was built in the 15th century. After the Charles V's conquest of Tunis, the Emperor came to Sicily. He entered in Palermo through this gate on 5 September 1535. In order to commemorate this event, the Senate of Palermo decreed to rebuild the gate in a more sumptuous style. The Viceroy of Sicily Marcantonio Colonna set off the construction in 1583. The gate was completed in 1584.
The gate was destroyed in 1667 because of a fire erupted inside the warehouse of the building. The Senate of Palermo commissioned the architect Gaspare Guercio to rebuild the gate. The work was completed in 1669.
The facade leading to the Cassaro has the typical style of the triumphal arches. The facade leading to the Corso Calatifimi and Piazza Indipendenza presents four big telamones depicting the Moors defeated by Charles V.
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.
