The Vilna Shul of Boston in partnership with the JGS of Greater Boston presents a three-part seminar on Jewish Nostalgia. Join one, two, or three adult learning lectures and Q&A with Rachel B. Gross, author of Beyond the Synagogue: Jewish Nostalgia as Religious Practice.   Participants can register for classes individually but the topics (Genealogy, Historic Synagogues and Jewish Delis) will build upon each other. Cost is $15 per session, $36 for all three.
