The Genoese Citadel is the main part of the town of Calvi, and its most important historical monument. It was a military outpost in the 15th century that helped guard the city against attacks from Franco-Turkish raiders to Anglo-Corsican armies. Inside the battlements, don’t miss the well-proportioned Caserne Sampiero, a military barracks that once served as the Genoese administration's seat of power, and the 13th-century Cathédrale St-Jean Baptiste, whose most celebrated relic is the ebony Christ des Miracles, credited with saving Calvi from Saracen invasion in 1553.
The citadel sits high above Calvi port from where it towers over the sea. From up here you get some great views of the coast and harbour.
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.
