Hohenzollern Castle
Hohenzollern Castle is a hilltop castle located on the Berg Hohenzollern, an isolated promontory of the Swabian Jura (NHN) above sea level, above and to the south of Hechingen, Germany approximately south of Stuttgart, capital of Baden-Württemberg. This mountain lends its name to the local geographic region, "der Zollernalbkreis", and is known among locals as "Zollerberg" (Zoller Mountain), or simply "Zoller".
Kyffhausen Castle
The Imperial Castle of Kyffhausen () is a medieval castle ruin, situated in the Kyffhäuser hills in the German state of Thuringia, close to its border with Saxony-Anhalt. Probably founded about 1000, it superseded the nearby imperial palace ("Kaiserpfalz") of Tilleda under the rule of the Hohenstaufen emperors during the 12th and 13th centuries. Together with the Kyffhäuser Monument, erected on the castle grounds between 1890 and 1896, it is today a popular tourist destination.
