Happy 4th of July! Walter Knott's personal labor of love, Independence Hall, is the nation's only brick-by-brick replica of the original in Philadelphia. Entering its hallowed halls, you'll feel as if you've stepped back into time. From the room where the Declaration of Independence was signed to the exact duplicate of the 2,075 pound duplicate of the Liberty Bell (complete with signature crack!), Independence Hall stands as a symbol of the hard work and determination of the men and women who made this great nation.
