Glienicke Palace was designed by Karl Friedrich Schinkel for Prince Carl of Prussia in 1826, The building, originally merely a cottage, was turned into a summer palace in the late classical style. Particularly striking are two golden lion statues in front of the frontage, which were also designed by Schinkel. The lions are versions of the Medici lions from the Villa Medici. In the palace are antique objets d'art, which the Prince brought back from his trips. The palace's park is now called the Volkspark Glienicke. The palace and park are UNESCO World Heritage sites as part of the Palaces and Parks of Potsdam and Berlin since 1990.
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.
