Genovevaburg is a castle standing on the southwestern side of Mayen in the German state of Rhineland-Palatinate. The castle is the symbol of Mayen and has been rebuilt several times since first being destroyed in 1689. Its name comes from a legend, according to which the seats of counts palatine, Siegfried and his wife, Genevieve of Brabant (German: Genoveva), were supposed to be on the same hill in (or above) Mayen. The earliest references linking the legend to this region date to the 17th century. Since when the castle and its bergfried, the so-called Golo Tower (Goloturm), have been linked to the legend is unknown.
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.
