1 Best Sight in Heidelberg and the Neckar Valley, Germany

The next stop after the castle on the Königstuhl funicular, Molkenkur was the site of Heidelberg's second castle. Lightning struck it in 1537, and it was never rebuilt. Today it's occupied by a small restaurant and guest house—which bears the creative name Schlosshotel Molkenkur—with magnificent views of the Odenwald and the Rhine plain from the terrace.
