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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
