Adenau is a town in the High Eifel in Germany. It is known as the Johanniterstadt because the Order of Saint John was based there in the Middle Ages. The town's coat of arms combines the black cross of the Electorate of Cologne with the lion of the lords of Nürburg. The northern loop of the Nürburgring lies just outside the town.

Nürburg is a town in the German district of Ahrweiler, in the state of Rhineland-Palatinate. It is also the name of the local castle, Nürburg Castle, which was built in the High Middle Ages. The castle is made of basalt which usually has black color. The well-known 24-kilometre (15 mi) racing track Nürburgring is nearby.
