Sorgenfri Palace was built by the architect Francois Dieussart in 1705-06 for Carl Count Ahlefeldt. From 1730, this country house was owned by the royal family, and Crown Prince Frederik (V) had court architect Lauritz de Thurah build a wing for the gentlemen of the Court and a horse stable. When Frederik V became king, the palace was given to his aunt, grand duchess Sophie Caroline of East Friesland, who let de Thurah demolish the main building in 1756-57 and build a new palace. From 1791-94, the heir apparent, Frederik (VI), expanded and modernised the palace.
Frederik VII later transferred the palace to the state. In 1898, the state placed the palace at the disposal of Crown Prince Christian (X) after modern conveniences and a glassed veranda were installed. Sorgenfri Palace was Christian X and Queen Alexandrine’s preferred summer residence, and both Frederik IX and the heir presumptive, Prince Knud, were born there. Prince Knud and his wife, Princess Caroline-Mathilde, lived in the Palace until their deaths in 1976 and 1995, respectively. Sorgenfri Palace is not open to the public, but part of the park is accessible to the public.
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.
