philadelphia_dts_2009_127Class ended by noon so a few of us headed to downtown Philadelphia to see Independence Hall and the Liberty Bell. One surprise was that the visible crack in the bell is not the “real crack,” but was purposely made to relieve stress on the two-ton behemoth. The real crack is almost imperceptible to the eye and runs from the top of the stress relief opening up to the word, “liberty.”

Neither was there a single event when the crack opened. When the bell was first shipped from the manufacturer in England, it cracked. It was recast in Philadelphia, but cracked again. The final crack apparently happened when it was rung for George Washington’s birthday.
