Diez's synagogue was desecrated in the November 1938 pogroms, when the interior was destroyed. The building was demolished after the war, in 1951. The Nazis also destroyed Diez's Jewish cemetery (built early 17th century). On this site now sits the tax office. A more recent Jewish Cemetery from the late 19th century survives and continues to overlook Diez from a hill above the town, all that remains of the Jewish history there.
