Arechi Castle is a castle in southern Italy located on top of a mountain, at the foot of which lies the city of Salerno.
The construction of the castle began in the 6th century under the Byzantine rule (the construction of the oldest part of the ramparts made of sandstone blocks is characteristic of this period).
Salerno was part of the Duchy of Benevento, which was the southernmost part of the Kingdom of the Lombards. When Charlemagne attacked the Lombards in the year 774, the Duchy of Benevento was ruled by Arechi II. He moved the main centre of power from Benevento to Salerno in order to strengthen his control over strategic areas such as the coastline and to secure communications within the province of Campania. During this period the castle was heavily fortified and its ramparts took the shape that have survived to our times.
Over the centuries, the castle had many owners. Archaeological work has identified, among other things, traces of the Norman presence. A watchtower was built north of the castle, allowing to conduct observations of the Gulf of Salerno.
Currently, the castle has been bought from the commune by a private company that arranged a restaurant inside. The defensive walls, however, are open to visitors free of charge, there is also a museum in the castle (large collections of coins and medieval ceramics were found during the renovation). At night, perfectly lit, it is visible from almost anywhere in Salerno.
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.
