Philadelphia National Constitution Center#
Founded in 1682, the city played a mayor role in the American Revolution as the meeting site for the Founding Fathers of the United States, who signed the Declaration of Independence in 1776 and the Constitution in 1787.
In the 19th century, Philadelphia became an important industrial center but decayed in the late 1960s experiencing an out-migration of manufacturing companies (and their job offers) to cheaper regions of the USA or overseas. The city recovered in the late 1990s when gentrification turned many neighborhoods into fashionable residential areas and stopped the trend of population loss.
Philadelphia's many universities and colleges have evolved the city into an educational and also economic hub and made it a top destination for international students. The city is also known for its arts, culture, and history, attracting about 40 million domestic tourists per year.
