History
Ringwall Grünbürg is an abandoned early medieval hilltop fortification in Germany above Stadtsteinach, built during the Carolingian–Ottonian period, the eighth through tenth centuries of Carolingian and Ottonian rule in central Europe. Its date is supported by medieval pottery and by the construction of the enclosure.
Dating and archaeological research
Since 1825, researchers have debated the age and character of Grünbürg, and excavations have taken place on the summit. The finds include prehistoric ceramic sherds as well as medieval ceramic pieces, indicating activity at more than one point in the site’s history. The recovered ceramics are held by the Landschaftsmuseum Obermain in Kulmbach.
Interpretations of the fortification
The prehistoric evidence and other findings show that Grünbürg was not a medieval motte castle, a castle built on a raised earth mound, and was not the predecessor of Nordeck Castle, a separate castle in the surrounding region. In 1950, historian Johann Schlund classified it as part of a chain of refuge forts. A refuge fort was intended to shelter people and possessions temporarily during danger rather than serve mainly as a permanent aristocratic residence. Schlund compared Grünbürg with the fortification on Staffelberg.
Remains
Summit setting and enclosure
The fortification occupies a mountain summit 521 metres above sea level. Steep slopes descend from three sides into narrow side valleys, providing natural protection. On the northeastern side, a saddle connects the summit with a neighbouring elevation. The ground falls only about 40 metres there before rising again to approximately 516 metres.
The oval interior measures about 155 by 85 metres and follows a northeast–southwest axis. A well-preserved inner ringwall, an enclosed defensive rampart or wall, surrounds the entire perimeter. It remains about one metre high, while its outer side drops roughly four metres to an almost continuous terrain step. This step falls by an average of four metres along an artificially steepened slope. Beyond it is an outer ringwall with a ditch between the wall and the terrain step. The outer ringwall now stands only about half a metre high, and both it and the intervening terrain step end on the northern side of the enclosure.
Entrances
Two entrances served the enclosure, one to the north and one to the south. At the northern opening, the inner ringwall alone forms the entrance, while slightly offset wall ends probably mark a secondary passage. The main gate stood on the southern side, where a forest path now passes through the fortification. There, the two ends of the inner ringwall turn five metres inward and create a passage five metres wide. The ends of the outer wall also curve slightly inward at this point.
