Liberty bell tattoo means freedom and justice. Philadelphia liberty bell is a bell located in Philadelphia, Pennsylvania. It is the main symbol of the American War of independence and also a symbol of freedom and justice. Traditionally, it was thought that the bell was famous for ringing it to summon the citizens of Philadelphia before the representative of the Continental Congress, Colonel John Nixon, read the declaration of independence on July 8, 1776, but historians questioned it because there was a serious problem in the spire of the parliament building where the bell was hung at that time.

The Continental Congress of 1774 and the battles of Lexington and Concord in 1775 rang the bell. Before 1837, the clock was called "independent clock" or "old Yankee clock". It was not until the rise of the anti slavery movement in the United States in the mid-19th century and the abolitionists hyped the inscriptions on the clock that the clock was called "liberty bell".
