The Liberty Bell, previously called the State House Bell or Old State House Bell, is an iconic symbol of American independence, located in Philadelphia. Originally placed in the steeple of the Pennsylvania State House (now renamed Independence Hall), the bell today is located across the street in the Liberty Bell Center in Independence National Historical Park. The bell was commissioned in 1752 by the Pennsylvania Provincial Assembly from the London firm of Lester and Pack (known subsequently as the Whitechapel Bell Foundry), and was cast with the lettering \"Proclaim LIBERTY Throughout all the Land unto all the Inhabitants Thereof\", a Biblical reference from the Book of Leviticus (25:10). The bell first cracked when rung after its arrival in Philadelphia, and was twice recast by local workmen John Pass and John Stow, whose last names appear on the bell. In its early years, the bell was used to summon lawmakers to legislative sessions and to alert citizens about public meetings and proclamations.
Today, the Liberty Bell weighs 2,080 pounds (940 kg). Its metal is 70% copper and 25% tin, with the remainder consisting of lead, zinc, arsenic, gold, and silver. It hangs from what is believed to be its original yoke, made from American elm. Although the crack in the bell appears to end at the abbreviation \"Philada\" in the last line of the inscription, that is merely the widened crack, filed out during the 19th century to allow the bell to ring. A hairline crack, extending through to the inside of the bell, continues towards the right and gradually moves to the top of the bell, through the word \"and\" in \"Pass and Stow,\" then through the word \"the\" before the word \"Assembly\", and finally through the letters \"rty\" in the word \"Liberty\". The crack ends near the attachment with the yoke. 781b155fdc
