The Reichenstein castle was built in 12th century at the northern end of the Hollmuth hill. In the 14th century it was acquired by the Palatinate but only one century later it was abandoned. On a 17th century engraving by Merian the castle is depicted as a ruin. Today, only some wall fragments are left. The castle complex has an almost rectangular grouned plan; it is saperated from the hill by a moat. The terracing was done at the beginning of the 20th century.
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.
