The Minčeta Tower was built by a local builder named Nicifor Ranjina and Italian engineers sent by Pope Pius II in 1463, at the height of the Turkish threat. Originally as a strong four-sided fort, it is the most prominent point in the defensive system towards the land. The tower's name derives from the name of the Menčetić family, who owned the ground upon which the tower was built. By its height and impressive volume, the tower dominates the northwestern high part of the city and its walls.
In the middle of the 15th century, around the earlier quadrilateral fort, Michelozzo built a new round tower using new warfare technique and joined it to the new system of low scarp walls. The full six-meter thick walls of the new tower had a series of protected gun ports. The architect and sculptor Giorgio da Sebenico of Zadar continued the work on the Minčeta tower. He designed and built the high narrow round tower while the battlements are a later addition. The tower was completed in 1464 and became the symbol of the unconquerable city of Dubrovnik.
After a long excavation, a 16th-century cannon foundry was discovered under Minčeta Tower. It is now a museum. Since Minčeta Tower is the highest point of the wall, it is considered to offer a seemingly 'unforgettable' view on the city.
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.
