Join us at the New Hampshire Historical Society on the Fourth of July for a special open house to celebrate America’s 250th birthday. Enjoy guided tours of the exhibitions and see rare objects from New Hampshire’s Revolutionary past, including two flags from the Second N.H. Continental Regiment. Learn 10 things you probably didn’t know about New Hampshire and the American Revolution. Participate in family friendly games and activities while enjoying the festive atmosphere of downtown Concord, with a parade at 9 a.m. and a ceremony at the State House at 10 a.m. The New Hampshire Historical Society is open from 11 a.m. to 1 p.m. on this holiday. Admission is free.
