Hohenzollern Castle. It was rebuilt in the 19th century. There was a spate of castle and even ruin rebuilding/construction in the 19th century.. Recently titled 'royalty' wanted ruins on their grounds. A bizarre result was the growth of experts in ruin construction LOL. Others wanted actual castles.
The Hohenzollern castle is a good example of revival castle construction and its mixture of stylistic elements and not a pure castle (as I would call it and what might pass as a defensive structure in the middle ages.)
Crac des Cheveliers would be closer to a pure castle (as I would call it).
