The ruin of Madenburg Castle is one of the biggest and oldest castle complexes in Rhineland-Palatinate. The castle was built on a cliff on the outskirts of the Palatinate Forest looking towards the Rhine rift valley.
In 1076 the Madenburg castle appears for the first time in a medieval document. Not a lot is known about the early owners of the castle, the counts of Madenburg. At a certain period it belonged to the Empire and to the Hochstift of Speyer. In 1470 Count Palatine Friedrich I. and his troops conquered Madenburg. In 1525, during the Peasants’ War, the castle was seriously damaged for the first time, but later rebuilt and renovated several times. In around 1689 French troops finally destroyed Madenburg.
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.
