Eltz Castle (Burg Eltz) is surrounded on three sides by the Elzbach River, a tributary on the north side of the Moselle. It is situated on a 70m rock spur, on an important Roman trade route between rich farmlands and their markets. It is still owned by a branch of the same family that lived there in the 12th century, 33 generations ago. The Rübenach and Rodendorf families' homes in the castle are open to the public, while the Kempenich branch of the family uses the other third of the castle. The Palace of Bürresheim (Schloss Bürresheim), the Castle of Eltz and the Castle of Lissingen are the only castles on the left bank of the Rhine in Rhineland-Palatinate which have never been destroyed.
The main part of the castle consists of the family portions. At up to eight stories, these eight towers reach heights of between 30 and 40 meters. They are fortified with strong exterior walls; to the yard they present a partial framework. About 100 members of the owners' families lived in the over 100 rooms of the castle. Platteltz, a Romanesque keep, is the oldest part of the castle. In 1472 the Rübenach house, built in the Late Gothic style, was completed. Remarkable are the Rübenach Lower Hall, a living room, and the Rübenach bedchamber with its opulently decorated walls. Between 1490 and 1540, the Rodendorf house was constructed, also in Late Gothic style. It contains the vaulted 'banner-room'.
The Kempenich houses were finished about 1530. Every room of this part of the castle could be heated; in contrast, other castles might only have one or two heated rooms. From 1965 to 1992, an engraving of Eltz Castle was used on the German 500 Deutsche Mark note.
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.
