Lichtenstein Castle, Germany: A Real-Life Fantasy Castle. by O Palsson Via Flickr: In my view, Lichtenstein castle in Baden-Württemberg is one of the most amazing castles in Germany. Small and compact with a single bright white main tower and perched on the edge of a huge cliff, it looks like something from an imaginary illustration or fantasy movie rather than a real structure. However, it is very real, and we went into the castle on a tour on our visit there last month. There has been a castle on that site since the 13th Century, but the present one seen in this picture was built by Duke Wilhelm of Urach in 1840.
