The Goloring is an ancient earthworks monument located near Koblenz, Germany. It was created in the Bronze Age era, which dates back to the Urnfield culture (1200–800 BCE.). 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.
