Wildenburg castle was built between 1202 and 1235 and is one of the few hill castles in the Eifel that has not been destroyed by war or demolition. It was the centre of gravity of a territorial lordship that extended in the west as far as the present border with Belgium and in the east reached the gates of Steinfeld Abbey.
Originally the castle and the village of Wildenburg were separated by a ditch and drawbridge. Today the ditch has been filled in and the drawbridge has disappeared. The castle itself comprises a main and forecastle. The most striking parts of the castle are undoubtedly the towers: the tall tower over the hall, the tower above the gate in the forecastle and the large square tower. The identification of the above towers is difficult, because all the towers visible today are round. The large fortified tower at the southwest corner was probably square at first, but was then reinforced against cannon-fire and rounded off. The so-called tall tower over the hall is today called the Johannisburg. It was bought by Steinfeld Abbey in 1715 and the old inner Palas was converted into a church, in which many wooden sculptures from various centuries are on display. The former staircase-tower became a bell-tower, around which are the gatekeeper's house, the witches' tower and the half-timbered houses of the village.
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.
