Burg Landshut
Take a walk up to the hilltop ruins of this 13th-century castle for splendid views along the Mosel. It was here that Trier's Archbishop Boemund II is said to have recovered from an illness by drinking the local wine. This legendary vineyard, still known as "the Doctor," soars up from Hinterm Graben street near the town gate, Graacher Tor. You can sample these Grand Cru wines at the castle's excellent restaurant (though be prepared to pay for the privilege) or pick up a bottle in one of the many shops below. The restaurant is open Friday to Sunday only for both lunch and dinner.
