The Electoral Palace was the residence of the last Archbishop and Elector of Trier, Clemens Wenceslaus of Saxony, who commissioned the building in the late 18th century. It was erected between 1777–1793. In the mid-19th century, the Prussian Crown Prince (later Emperor Wilhelm I) had his official residence there during his years as military governor of the Rhine Province and the Province of Westphalia. It now houses various offices of the federal government.
The Electoral Palace is one of the most important examples of the early French neoclassical great house in Southwestern Germany, and with Schloss Wilhelmshöhe in Kassel, the Prince Bishop's Palace in Münster and Ludwigsburg Palace, one of the last palaces built in Germany before the French Revolution. Since 2002 it has been part of the Rhine Gorge UNESCO World Heritage Site, and it is also a protected cultural property under the Hague Convention.
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.
