Drakensteyn is a small castle constructed in the years 1640–1643 for a Gerard van Reede Läm. A house called Drakesteijn at this location was first mentioned in 1359. It is owned by Princess Beatrix of the Netherlands, the country's former Queen who abdicated in 2013. Beatrix bought the castle in 1959, when she was the heir to the Dutch throne, and took up residence in 1963. After her marriage in 1966 she continued to live there with her husband, Prince Claus and later their three sons as well. After Beatrix succeeded her mother Juliana as Queen of the Netherlands in 1980, the family moved to The Hague in 1981. The royal connection aside, its most distinctive feature is its octagonal shape. It is surrounded by a moat that can be crossed via a bridge. Its style can be described as Classicist.
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.
