The Vieux-Port (Old Harbour), is at the heart of La Rochelle. Enclosed by its mighty medieval towers (Saint Nicolas and La Chaîne), the picturesque harbour is now lined with seafood restaurants and bars.
Since the 13th century, the port of La Rochelle has occupied this site. It is likely that from the beginning it was fortified. The remaining towers date from the 14th and 15th centuries. They survived the destruction of the enclosure after the siege of 1628. On each side of the entrance, the Saint Nicolas tower, the highest, and the La Chaîne, and further on, linked to the latter by a curtain wall, the Lantern tower, both a lighthouse and a prison.
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.
