In addition to tours, the Concord School & Upper Burying Ground will host its eighth annual Bell Ringing Ceremony at 2 p.m. A tradition that began in the 18th century and was revived in 2005, the bell ringing commemorates America's enduring freedom by tolling one peal for each year of our nation's independence since 1776.
