The Truro Historical Society has planted its Three Sisters Garden on the lawn of the Cobb Archive at 13 Truro Center Road in tribute to the Wampanoag peoples. The three sisters — corn, beans, and squash — represent crops that were essential to many Native American communities. Visit the Cobb Archive on Wednesday, July 15, at 4 p.m. for a live history talk with Marcus Hendricks of the Wampanoags. To register, email [email protected]. Fee $10 per person. Be sure to bring a lawn chair.
