I want to know whether a non-Jew can, according to Jewish law, enter and visit a Jewish cemetery, to know what it looks like and what symbols and images are used in the cemetery, for personal knowledge.
Non-Jews can come to the service at the cemetery to honor the person. So I would presume they can come be in the cemetery as long as they ask at the front for any respectful instructions (such as walkable areas.) Non-Jews as well as Jews visit the famous graves of patriarchs and matriarchs in Israel. Hope that helps.
