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".
Hohenheim Castle
Schloss Hohenheim is a manor estate in Stuttgart, eponymous of the Hohenheim city district. 
The original castle was a fief of the County of Württemberg, recorded for the 12th century. The estate fell into the possession of Charles Eugene, Duke of Württemberg in 1768, who had it re-built as a Rococo style manor with extensive gardens and residential palace for his future wife, Franziska von Hohenheim. The estate was the main ducal residence during 1772–1797, when it fell to the city of Stuttgart.
An "Agricultural Educational Testing and Model Institution" was housed here in 1818, 
and the estate remains in use by the Horticulture and Agriculture Departments 
of the University of Hohenheim.
