The Goloring is an ancient earthworks monument located near Koblenz. It was created in the Bronze Age era, which dates back to the Urnfield culture (1200–800 BC). During this time a widespread solar cult is believed to have existed in Central Europe.
The Goloring consists of a circular ditch of 175 metres in diameter with an outside embankment extending to 190 metres. Technically this makes the structure a henge monument, although the use of the term henge outside of Britain is sometimes disputed. The outside embankment is approx. 7 metres wide and 80 cm high. The ditch has an upper width of 5–6 metres and is approx. 80 cm deep. In the interior one can find a roughly circular leveled platform, which is about elevated by about 1 metre. The platform has been created based on piled gravelled rock and has a diameter of 95 metres. Remnants of a 50 cm thick wooden post with an estimated height of 8–12 metres were excavated in the middle of this platform.
The design of the ditch is unique in Germany, and makes the earthworks similar to many British monuments of the same era. It is often compared to Stonehenge in England, which has similar diametric proportions.
Goloring is located within the boundaries of a former military dog training camp, but was acquired by the town of Kobern-Gondorf in June 2004. The Goloring is currently not accessible to the general public but there are plans under way to build a historic park with the earthworks at its centre.
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.
