Elmstein Castle was built in the 12th century as a Palatine castle in order to guard the route through the valley. The feoffees held the title of Schenk, a German aristocratic title that originally meant cup bearer. The castle occupied by the Electorate of the Palatinate. Between 1220 and 1230, the lower curtain wall was built. Emperor Louis IV of Bavaria ceded the castle to his cousin, the Count Palatine. From 1419 to 1437, the castle was occupied by Count John V of Sponheim. In 1466, the castle was enfeoffed by Frederick I the Elector, to Erhard of Remchingen. In 1513, in the course of changes of ownership, Henry of Pagk was given the castle as a fief. During the German Peasants' War in 1525 the castle was damaged. Count Palatine John Casimir inherited the castle in 1576. The castle was also damaged during the Thirty Years' War in 1648. In 1689, during the War of the Palatine Succession, the castle fell into a permanent state of disrepair. Since then, the castle has been in private ownership.
The remains of the parts of the original curtain walls, the palas and the shield wall are still able to be seen today.
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.
