This is a puzzle in the series of 3D puzzle Ravensburger. With this puzzle of 216 pieces Neuschwanstein Castle can be reconstructed. The pieces are made of plastic.
The castle was originally called the Neue Burg Hohenschwangau, got its current name in 1886 after the death of Louis. The first name returned to the castle of the Lords of Schwangau who was in the same place. The medieval castle Schwanstein stood on the site of the present Hohenschwangau.
Tourists can walk upwards or (as the king) will show up by carriage carry. That one often called a fairy tale castle Neuschwanstein, may have to do with the fact that Sleeping Beauty Castle at Disneyland in California is based on Neuschwanstein Castle. Walt Disney himself visited Neuschwanstein before the construction of its first theme park began.
