It's clear how much Americans treasure the Liberty Bell from the moment you see the size of the centre dedicated to this object alone. The bell, which features a famous crack, was once heard ringing out over Philadelphia, announcing the first public reading of the Declaration of Independence on 8 July 1776. However, this isn't why the Liberty Bell was cast before this, it had rung from the building now known as Independence Hall to mark various occasions. Its current moniker wasn't applied to the Liberty Bell until the 1830s, when anti-slavery protesters adopted it as their symbol. The bell is now seen across the United States as a representation of freedom.
The bell itself is the last thing in the exhibition, but don't rush through to the end. Visitors must first make their way through tight security checks. After this, various written, photo and video displays explain why and where the bell was cast, as well as the mystery behind its cracking. Also, visit the interesting section on why the famous inscription on the bell spells “Pennsylvania” incorrectly.
The Liberty Bell is displayed beautifully under a grand glass roof. It is 70% copper and 25% tin, with the rest of it being made from various materials, including silver, zinc and arsenic. Its backdrop is Independence Hall, home to the bell until 1976. Photos are permitted, although due to the sheer amount of visitors, you may have to wait a while to get the right angle. You can also view the Liberty Bell outside the centre, through the glass.
The Liberty Bell Centre is in central Philadelphia and is part of the National Historical Park. Open everyday, entrance is free, and you don't need to book prior to arrival.
