Fort San Lucian is a large bastioned watchtower and polygonal fort in Marsaxlokk, Malta. The original tower was built by the Order of Saint John between 1610 and 1611, being the second of six Wignacourt towers. An artillery battery was added in around 1715, and the complex was upgraded into a fort in the 1790s. In the 1870s, the fort was rebuilt by the British in the polygonal style.
Saint Lucian Tower is the second largest watchtower in Malta, after Saint Thomas Tower. Today, the tower and fort are used by the Malta Aquaculture Research Centre.
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.
