The ancient Agora of Argos started to be organized during the 5th century BC. in the south of the city, on the crossroads from the Heraion of Argos, Corinth and Tegea. The architectural programme was completed at the end of the 4th century BC. During the Classical and the Hellenistic periods, the Agora was surrounded by porticos and buildings which can hardly be distinguished at present under the later architectural phases.
During the Roman times, many of the existing buildings were altered in shape and function, mostly into shops and fountains when, in the 2d and 3d century A.D. a general remodeling of the site took place. Later, during the 4th century A.D., a last monument of Paganism was built, a hearth surrounded by boundary steles from the enclosure (peribolos) of an 'heroon' of the Archaic period dedicated to the 'Seven against Thebes'. The invasion of the Goths, in 395-396 A.D. accelerated the destruction and the disappearance of the monuments of the Agora.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
