Mantua Cathedral (Duomo di Mantova) is the seat of the Bishop of Mantua. An initial structure probably existed on the site in the Early Christian era, which was followed by a building destroyed by a fire in 894. The current church was rebuilt in 1395–1401 with the addition of side chapels and a Gothic west front, which can still be seen in a sketch by Domenico Morone (preserved in the Palazzo Ducale of Mantua). The bell tower has seven bells.
After another fire in the 16th century, Giulio Romano rebuilt the interior but saved the frontage, which was replaced however in 1756–61 by the current Baroque one in Carrara marble. Notable characteristics of the Renaissance structure are the cusps, decorated with rose windows on the south side, which end at the Gothic bell tower.
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.
