Mainz, was an important center of rabbinical scholarship during the Middle Ages. This attractive town on the Rhine was home of Rabbi Jacob ben Moses Moellin (the Maharil), as well as of the eminent Kalonymus dynasty of rabbis. The small Mainz Synagogue is an architectural gem. Its ark contains three Torah scrolls that survived Kristallnacht. The Mainz Regional Museum displays several 12th century Jewish tombstones. Today’s community was reborn by Holocaust survivors in 1945.
