Germany(Rhineland-Palatinate) - Trier

Trier historically called Treves in English, is a city in Germany on the banks of the Moselle. It may be the oldest city in Germany, founded in or before 16 BCE (contested with Worms, Kempten, and Cologne). Trier lies in a valley between low vine-covered hills of ruddy sandstone in the west of the state of Rhineland-Palatinate, near the border with Luxembourg and within the important Mosel wine region.

Eltz Castle  is a medieval castle nestled in the hills above the Moselle River between Koblenz and Trier, Germany. It is still owned by a branch of the same family (the Eltz family) that lived there in the 12th century, 33 generations ago. Bürresheim Castle (Schloss Bürresheim), Eltz Castle and Lissingen Castle are the only castles on the left bank of the Rhine in Rhineland-Palatinate which have never been destroyed.
