Floods can’t keep the Granite Center of the World down. Barre’s annual Heritage Festival is a stone-cold blowout this year, with reopened businesses and institutions offering a packed schedule of events celebrating the town’s history, culture and resilience. Guests tour the Rock of Ages quarry, the Barre Opera House and the Vermont Granite Museum; chow down at the food trucks in Currier Park; jam out to the head-banging tunes of Rock City and Atom & the Orbits at a flood-relief benefit concert; and enjoy countless other performances, art shows, readings, dance parties and beer gardens.
