Agliè's main attraction is its Castello Ducale, one of the Residences of the Royal House of Savoy, listed in the UNESCO World Heritage Sites. Dating from the 12th century, it was originally a possession of the counts of San Martino. In the 17th century, it was turned into a rich residence by count Filippo d'Agliè, but was ravaged during the French invasion of 1706.
In 1765 it was acquired by Charles Emmanuel III of Savoy and sold to his son Benedetto of Savoy who had it radically renewed ten years later, under design by Ignazio Birago di Bòrgaro. Thenceforth it was a summer residence for the Kings of Sardinia. It was sold to the Italian state in 1939.
It has a monumental façade with two stairs and a fountain; the interior includes 300 rooms, mostly provided with contemporary furniture. The castle is surrounded by large English- and Italian-style gardens. It was used as the location for the Italian series Elisa di Rivombrosa as Rivombrosa.
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.
