Wirtemberg Castle, a ruined hilltop castle, is the second family seat of the House of Württemberg, whose ancestors had abandoned Beutelsbach Castle (also known as "Kappelberg Castle"). Built on the eponymous Württemberg mountain in a spur of the Schurwald around above sea level, it is located in the current municipality of Rotenberg in Stuttgart, between Bad Cannstatt and Esslingen am Neckar. Between 1080 and 1819, three castles with this name existed in the area. Read more on Wikipedia
