Rhineland-Palatinate is a southwest German state bordered by France, Belgium and Luxembourg. The state capital, Mainz, features Jewish synagogues and cemeteries, the Romanesque Mainz Cathedral with ornate tombstones, and the Gutenberg Museum devoted to the inventor of the printing press. The lush Moselle Valley, with its riverside towns of Piesport and Bernkastel-Kues, is one of Germany’s largest wine regions.
