Don't be fooled by the dressed up actors and the building facade - the Betsy Ross House was largely reconstructed for the Bicentennial in 1976. Regardless of how much is original, how much is recreated and how much is "of the period", the experience is a good one.
Walk through the colonial house to learn more about Betsy and what her life was like when she was asked to sew a flag for our new nation (the flag that is often associated with her name is not actually the design she used as it took a while for the nation to have 13 states...and then the number jumped to 16 fairly quickly). Check out the first floor exhibit of works sewn by her descendants -- apparently the talent was passed on!
Cute gift shop and frequent (free) performances in the courtyard at the entrance.
There is an entry fee (minimal) and an audio guide is available.
