Rydboholm Castle (Rydboholms slott) dates back to the Middle Ages. The castle, with the three interconnected wings around an open courtyard, dates from the 16th century. The main building was built in 1548. The castle was reconstructed during the 18th century. Southwest of the castle is a large park in English style from the early 19th century, built by Magnus Fredrik Brahe.
From the 15th century, Rydboholm was the property of members of the Sture family, followed by the Vasa dynasty and later the Brahe family. According to some sources Gustav I of Sweden, who was King of Sweden from 1523 until his death, was born at Rydboholm Castle. From 1520, it belonged to his sister, Margareta Eriksdotter Vasa.
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.
