Forte Sperone is the heart of Genoa's 19th-century fortifications, located right at the apex of the 'Mura Nuove' (new walls) from 1630, which to this day take the shape of mighty ramparts nestled in the hills behind the city centre.The fort's main entrance, with the Savoy coat of arms above it, is protected by a moat and a heavy gate that was once connected to a drawbridge via two chains; other important architectural elements include a well-preserved gunpowder magazine, located in the lower part of the fort, central barracks with large rooms, and a beautiful little chapel attached to the complex.
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.
