Needless to say, the fame of the Liberty Bell is so great that it feels like it can be a must-visit place in Philadelphia, just like the Independence Palace. It seems that every time I come to Philadelphia, I will repeat the ritual of checking in. The two are very close, just walk across the road. The exhibition hall is open to the public for free, and there is no need to buy tickets. The Independence Palace needs to be booked in advance on the official website, with a ticket booking fee of 1 yuan. The Liberty Bell has an independent exhibition hall for visiting, and the entrance requires security check. You can visit it up close and walk to the Liberty Bell. It was previously possible to circle 360 degrees, but this time it was only open 180 degrees, and the other half was blocked, but the advantage is that you can unlock a Liberty Bell with no one in the background.
The Liberty Bell was originally in the palace of the Independence Palace, and then it was displayed in the memorial hall on the lawn because the bell body cracked. This time, the display stand at the visitor center was also empty. Another knowledge point was that cracks first appeared when it was transported to Philadelphia in 1752, and then after several repairs, there were still cracks, so they gave up repairing it. And it was this bell that rang on July 4, 1776. The Liberty Bell has also been relocated several times. Although the locations of each relocation were not far away, people were still worried that there would be more serious cracks. They also installed a micro-variable displacement sensor on the bell that can test the movement of one millionth of a meter to test whether it is suitable for relocation. Every visit seems to unlock different little knowledge points, which is probably one of the pleasures of traveling.
