The highest point in Pennsylvania is located on Mount Davis, which sits along the Negro Mountain ridge near the Maryland border. It was named after John Nelson Davis, an early settler and former owner of the site. He was also an American Civil War veteran, land surveyor and naturalist. In terms of high points in the United States, this one is pretty straightforward and easy to get to.
The city of Pittsburgh is located in southwestern Pennsylvania at the junction of three rivers. It is often referred to as Steel City because of its hundreds of steel-related businesses. It is also known as the City of Bridges as there are 446 of them, which is more than any other city in the world. Pittsburgh provides plenty of opportunities to step back in time to learn about its history, appreciate American art and just enjoy the skyline.
Philadelphia served as the capital of the United States for nearly a decade towards the end of the 18th century. It was here in the Philadelphia State House (more commonly known today as Independence Hall) where both the Declaration of Independence and the Constitution were vigorously debated and ultimately drafted and signed by the founding forefathers of the United States. It was also here in that same State House where the Declaration of Independence was read out loud to the public for the first time on July 8th 1776. But that wasn't the only "first" for the city of Philadelphia. It is home to the first university, the first zoo, the first art institution, the first hospital, and the first public library in the United States.
