The ring wall system is located at the end of a spur of the Burggrafenberg (282.8 m above sea level), which points to the mouth of the Burgholzbach valley in the Wupper valley. The facility is located in the middle of the forest in the lower third of the Burggrafenberg at 227 m above sea level.
The entire system, including an upstream moat, is 600 m long. Towards the west it is closed by an approx. 180 m long rampart, the inner wall with a ditch is about 65 m long and 18 m wide. It is unclear whether this matrix was built at the same time. The walls have a wall core with mortar. An access cannot be recognized; Rafael von Uslar assumes that it is an Upper Franconian defense system with a bridge over the moat.
The ring wall is located in a forest area called Schimmelbusch near Müngsten, on the southern slope of the Morsbach valley, above the mouth of the Morsbach into the Wupper. Not far from the height of the ridge, the Wallburg stretches out as an uneven square with straight edges.
The Oberburghof ring wall system is a ring wall system from the early or high Middle Ages near the village of Oberburghof in Hückeswagen . It is located on a castle hill in the forest area of the Mul . The ring wall, also called Borberg, lies on a mountain tongue that slopes down into Siefen on three sides . The rising terrain to the northeast is sealed off by three walls with ditches. Possibly, but not proven, a connection with the nearby ore smelting in the Mul area.
The wall is a medieval fortification that has been declared a ground monument. Only remnants of the section wall are preserved. It was built directly at the former confluence of the Dörpe brook into the Wupper . The wall was 40 meters long, in front of it was a ten meter wide trench. The rock massif is located at a height of 280 meters above sea level.
According to a study carried out in 1968 using the radiocarbon method , the system dates from 310 ± 80 BC. AD. At that time lived Sugambri in the area.
The Eifgenburg is a former hillside castle in Burscheid. It is an early medieval fortification from the 10th century. The dating took place after the discovery of pottery shards. It served as a refuge and shelter. The protected remains are on the right bank of the Eifgenbach .
Oval castle hill, extensive wall and ditch system in the Scherfbachtal on the road from Odenthal to Bechen. Probably an older knight seat of the Lords of Scherf.
A castle hill more than four meters high has been preserved. Probably the oldest knight residence of the Lords of Forsbach, which was first documented in 1373. In the late Middle Ages, they built a permanent house not far away in the area of today's Halfenhof.
Holterhöfchen is a medieval building in the town of Hilden ( Mettmann district ). The system appears as a double ring wall with an intervening section wall in the S-part. There is also a remaining brickwork in a square plan, which is also probably medieval (9th to 10th century).
The Motte Schwanenmühle, also popularly known as "Schwanenburg", is an early / high medieval fortification in the Langenfeld district of Wiescheid on the city limits of Solingen on the western edge of the Bergisches Land (North Rhine-Westphalia). The ramparts and the actual Motte tower hill for the lord's residential tower are still preserved from the complex.
