The Declaration Of Independence was signed in Philadelphia in 1776.
Although the wording of the Declaration was approved by Congress on July 4, the date of its signing has been disputed. Most historians have concluded that it was signed nearly a month after its adoption, on August 2, 1776, and not on July 4 as is commonly believed.
