San Juan de las Águilas Castle dates from the 18th century, although its origins go back to the Carthaginian period. After the expulsion of the Arabs, the castle was abandoned.
Its reconstruction was tackled at a later date but not quite successfully until King Charles I of Spain (1530) ordered, by Royas Decree, ist rebuilding with the aim of guarding the coastal strip between Vera and Mazarrón, which was threatened by Turkish and Algerian raids. The building work on this castle was tackled again in 1579, under the reing of Philip II. The Torre de las Aguilas (The Eagles Tower) was built in this period. Its last remodelling would be undertaken under Charles III (in the 18th century), who decided to extend the fortress due to the town's incresing population and the constant Berber attacks to which the port and its population were subjected.
This new remodelling turned it into one of the best fortified castles of this period.Currently, there are very few remains of the splendour of this fortress. A coat of arms, where Castile¿s lions might be represented, can still be observed in one of the preserved façades. Recent excavations have revealed underground passages in the surrounding area, which, according to popular beliefs, used to connect this castle with another fortress of the municipality, the Castle of Tébar. In addition to the fortress, also of tourist interest is the panoramic sight of the city of Aguilas that can be admired from its location.It was restored in 2007 and opened as a museum in 2009.
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.
