If you're a member of the tribe, or simply aren’t down for an egg hunt, spend your Easter Sunday scouring the Lower East Side for historical treasures. Each year Big Onion uses the day of Jesus Christ’s supposed resurrection to rekindle 150 years of Jewish history in the land of tenements. Tour highlights include the Eldridge Street Synagogue, the Jewish Daily Forward building, and the founding sites of the Hebrew Immigrant Aid Society and B’nai B’rith, the world’s oldest Jewish service organization. Meet at the southwest corner of Delancey and Essex Sts, in front of Chase Bank. Subway: F to Delancey St; J, Z to Delancey–Essex Sts.
