It is a famous historical symbol in Philadelphia, representing the spirit of freedom and independence. Originally commissioned by the Pennsylvania State Legislature in 1752, the Whitechapel clock factory in London, England, was used to hang in the spire of the State Capitol building (now Independence Hall). The clock face is engraved with the famous quote from the Bible: 'Declare freedom to all people in the world', reflecting the pursuit of religious freedom and social justice at that time. It played an important role in American history, especially during the American Revolutionary War when it was used to declare significant events, such as the public reading of the Declaration of Independence on July 8, 1776.
