About 1300, a knight named Conrad von Tronecken is mentioned in document for the first time, and then somewhat later the Feste Troneck (fortification), which, however, is probably much older. Having been destroyed several times, by Cologne, Imperial and French troops, and then finally by an earthquake, only remnants of Dhronecken castle are left now, although a corner tower can still be climbed.
On the old castle's foundations in modern times, commercial buildings were built, and also a bigger, tall building – called the Schloss – which is today used as a forester's office. Also, a barn with beam construction serves as a community centre for the municipality of Dhronecken. The attractively laid-out castle gardens have been continuously planted and tended since 1985.
Below the castle is found a nature play area on both sides of a brook. A ford with stepping stones, a forumlike playing and gathering place on a slope, made out of mighty stone blocks, wooden footbridges over wetlands left in their natural state, playing houses, a suspension bridge and a monorail are the great attractions not only for children, but also for adults.
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.
