The Borgo Medioevale in Turin, Italy, is an open air museum and reconstructed medieval village and castle. It is located in the Parco del Valentino (Valentino Park) on the riverbank of the Po river. It was built for the 1884 Italian general exposition and it was constructed by replicating and mimicking late-medieval architecture of the Piedmont region.
The reconstructed architecture, decorations, and landscaping followed strict criteria of faithfulness to historical models. Over 40 sites (including castles, villages, and churches) all across Piedmont and Aosta Valley were used as models and many intellectuals, historians, artists and technicians took part in the project. Among the structures that served as models are Fénis Castle, Issogne Castle, Verrès Castle, and Ivrea Castle.
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.
