There is archeological evidence of a Jewish presence in Trier in the 3rd and the 6th century. The oldest Jewish site is the Jews’ Lane, located just off the city’s main market. It is a short and narrow street of medieval houses that leads into the Main Jewish Square where the medieval community hall and synagogue stood. Today’s Karl-Marx-Haus Museum is perhaps Trier’s most visited site. Today’s Jewish community worship in the Synagogue, one of the most attractive built in post-war Germany.
