The Liberty Bell
The Liberty Bell is a symbol of freedom. It was made in London and taken to Philadelphia in 1752 where it cracked when it was first used. It was repaired, and when the Declaration of Independence was signed, it rang out the day. It cracked again in 1835 and 1846. In 1976 it was placed in a special case of glass and steel behind Independence Hall (the building in Philadelphia where the Declaration of Independence was written and signed).
Stars and Stripes
The flag of the US has 13 stripes for the 13 original colonies and 50 stars for the 50 states. American citizens and immigrants sometimes recite the Pledge of Allegiance to the flag: 'I pledge allegiance to the Flag of the Unites States of America and to the Republic for which it stands, One Nation, under God, indivisible, with Liberty and Justice for all.'
