The Udine castle hill is made of drift accumulating during centuries. However, a legend about its origin says that when Attila the Hun (also called the Scourge of God) plundered Aquileia (one of the biggest cities of the Roman Empire at that time) in the year 452, he asked his soldiers to build a hill to see the Aquileia burning. This was made by filling the helmet of each soldier with ground.
The first official statement of the existence of a building on the hill dates back to 983: the Holy Roman Emperor Otto II donated to Rodoaldo, Patriarch of Aquileia a castrum, a military building.
The present building has the form of a palace and it was built on the ruins of a fortress destroyed in the year 1511 Idrija earthquake. The construction had started in 1517 and the works had lasted for 50 years. The external decoration of the palace and the paintings in the Parliament Hall are due to Giovanni da Udine, one of the pupils of Raphael.
The council of the Patria del Friuli was one of the first parliaments in the world, and it was suppressed after the French occupation in 1797.
Today the castle hosts the History and Art Museum of the City of Udine.
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.
