NEUSTADT: an der Haardt (Haardt Mountains), 67433 Rhineland-Palatinate
and (sic) was changed to Neustadt an der WeinStrasse (a road on the eastside of the Haardt Mountains from Schweigen on the French border to the north past Bad Duerkheim)
It is very old, going back into the early 1700's at least! Some sandstone tombstones are so old that it is rather difficult to determine the engravings. I visited it in September 1984 and found it in very good shape. It is in the east part of town, off MaximilianStrasse.
The cemetery, synagogue memorial and the adjoining synagogue auxiliary building are now maintained by: Juedische Kultusgemeinde der Rheinpfalz, LudwigStrasse 20 (location of synagogue memorial and auxiliary building), 67433 Neustadt an der WeinStrasse; phone 06321/2652.
New graves (since the end of WW2) of Jews that moved away are also found there. Family photos available. He (?) will do data entry of names. Source: Ernest Nathan, 2615 Guenevere Ave, Huntsville, AL 35803-1935; Phone: 205/881-2586
