The Norwalk Historical Society's mission is "research, preservation and promotion of interest in the city of Norwalk." The society is located in the Mill Hill Historic Park overlooking Wall Street.
NHS provides plaques for architecturally significant buildings in Norwalk and educates Norwalk third-graders about the early history of Norwalk through the Little Red Schoolhouse Program, featuring volunteers dressed in colonial garb.
NHS also hosts the Colonial Harvest Festival, the 4th of July Bell Ringing ceremony and other special events. Mill Hill Historic Park features three historical buildings—the Norwalk Town House, the Governor Thomas Fitch Law Office and the Downtown District Schoolhouse—as well as the Mill Hill Burying Ground. Volunteers and donations are welcome.
