Burg Metternich
On the opposite shore of the river, the romantic ruins of this medieval-era castle crown the Schlossberg (Castle Hill) vineyard. The Lords of Braunshorn are named as owners of Metternich as far back as 1268, but the core of the castle is probably even older than that. Enjoy a glass of wine or a hearty meal in the castle's terrace café, then take a stroll down to the village of Beilstein. It's known as "Sleeping Beauty of the Mosel"; once you ascend the Klostertreppe (monastery steps) to the baroque monastery church for views of the winding streets lined with half-timber houses, you'll understand why.
