Neuschwanstein Castle, Hohenschwangau, Bavaria, Germany

One was called Schwanstein Castle. In 1832 Ludwig's father King Maximilian II of Bavaria bought its ruins to replace them by the comfortable neo-Gothic palace known as Hohenschwangau Castle. Finished in 1837, the palace became his family's summer residence, and his elder son Ludwig (born 1845) spent a large part of his childhood here.
Vorderhohenschwangau Castle and Hinterhohenschwangau Castle sat on a rugged hill overlooking Schwanstein Castle, two nearby lakes (Alpsee and Schwansee), and the village. Separated only by a moat, they jointly consisted of a hall, a keep, and a fortified tower house. In the 19th century only ruins remained of the medieval twin castles, but those of Hinterhohenschwangau served as a lookout place known as Sylphenturm.
