Built in 1296, Ehrenberg Castle offers everything you would expect from a medieval castle, defensive walls, tall towers and a lot of history. The gothic castle complex was home to emperors and kings, princes and tzars.
Ehrenberg was in the center of wartime battles several times. In 1546, the Protestant Schmalkalden occupied the fortress. In 1552, it was taken by the Elector Moritz of Saxony. In 1632 the Swedes stopped in front of its walls. In 1703, Ehrenberg fell into the hands of the Bavarians during the War of the Spanish Succession. From 1716 to 1717, Ehrenberg became the exile of Russian Tsarevich Alexei, who fled from his father, Tsar Peter the Great. Even in the Napoleonic Wars, it played a role. Beginning in 1971, Fridolin Schennach from Reutte took over the condemned ruin and initiated a rescue operation with numerous other idealists.
In 2014, the world's longest pedestrian suspension bridge was completed between the Ehrenberg Castle ruins and Fort Claudia, spanning the strategically important pass that these two structures were in part meant to guard. The length of the bridge 403 meters, with a height of 110 meters.
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.
