The Liberty Bell originally hung in the tower of Independence Hall across the street.  It continued to be used after the initial cracking when the fracture was enlarged to allow the bell to ring properly.  However, additional cracking near the suspension point of the bell brought its useful life to a close.  A new tower bell was installed and the Liberty Bell displayed in stair hall of Independence Hall. 

With the increasing number of visitors eager to see the bell, it was decided to erect a glass pavilion on the mall for its display.  Visitors can view the bell from outside when the Liberty Bell Center is closed or crowded.
