About Pennsylvania

Location map of Pennsylvania state USA
Where in the United States is Pennsylvania? Location map of Pennsylvania in the US.

Pennsylvania, officially the Commonwealth of Pennsylvania, is a state in the Mid-Atlantic region in the northeast of the United States; the landlocked state features a 70 km (43 mi) short shoreline at Lake Erie.

Pennsylvania borders New York in the north and northeast. The Delaware River forms sections of its eastern border with the US states of New York and New Jersey. In the south, the state is bounded by West Virginia, Maryland, and Delaware, and in the west by Ohio.

Early Days of Pennsylvania
In 1682, an English real estate entrepreneur named William Penn obtained sovereign control of the area with all rights and privileges (except the power to declare war). Pennsylvania was one of the 13 original colonies that abandoned the rule of the English Crown and later formed the United States. Pennsylvania ratified the U.S. Constitution on 12th December 1787 as the second state, after Delaware.
Pennsylvania attempted to be first to sign the constitution in the hope of securing the seat of the National Government in Pennsylvania. The Pennsylvania State House (now known as "Independence Hall") in Philadelphia was the seat of the American government during the revolutionary and early national years.

Some Geography

Pennsylvania Topographic MapTopographic Regions Map of Pennsylvania. (click map to enlarge)
With an area of 119,279 km² (46,054 sq mi) [1], Pennsylvania is ranked 33 in the US list of the largest states, about one third the size of Germany.
Compared with other US states, New Jersey would fit into Pennsylvania more than five times. However, Texas is almost six times larger than the Quaker State (Pennsylvania's nickname).

The Appalachian Mountains, an eroded mountain chain in eastern North America, dominate Pennsylvania's landscape.

Pennsylvania was home to two of the largest steel producers in the world; Pittsburgh-based U.S. Steel and Bethlehem-based Bethlehem Steel. The former blast furnace sites have either been destroyed, preserved, or in the case of Bethlehem, became a new multi-million dollar Sands Casino Resort in 2009 with a revenue of US$ 14.5 billion (FY 2014).

The landscape in the interior of the Commonwealth is dominated by the various land forms of the Appalachian Mountains. The northwestern part of Pennsylvania is characterized by the large dissected Allegheny Plateau and the Allegheny Mountains in the center of the state. Lake Erie Plain in the northwest is a narrow region along Lake Erie.

Highest point
Mount Davis in the Forbes State Forest, at 979 m (3,213 ft), is the highest point in the Commonwealth.

Major rivers in Pennsylvania. The Allegheny River joins with the Monongahela River to form the Ohio River in Downtown Pittsburgh. The Delaware River defines the eastern border of the Commonwealth with New York State and New Jersey. The Susquehanna River, one of the oldest existing river systems in the world, is formed from two main branches: the "North Branch," which rises in upstate New York, and the "West Branch," which originates in the Allegheny Mountains in western Pennsylvania. The Schuylkill River and its tributaries drain major parts of the center-southern and easternmost Coal Regions in the state before joining the Delaware River.

Major lakes in Pennsylvania are the Allegheny Reservoir (also known as Kinzua Lake), a human-made lake along the Allegheny River. The Raystown Lake, a reservoir at the Raystown Branch of the Juniata River, is the largest lake that is entirely within the state. Pennsylvania has a shoreline at Lake Erie, the fourth-largest lake (by surface area) of the five Great Lakes in North America.

Pennsylvania has one UNESCO World Heritage Site. The Independence Hall official website in Philadelphia is the building where both, the United States Declaration of Independence (1776) and the Constitution of the United States (1787), were argued and adopted.

The universal principles of freedom and democracy described in these documents are of fundamental importance to American history. They have also had a profound impact on law-makers around the world.

The Independence Hall was completed in 1753 as the colonial legislature for the Province of Pennsylvania. It was used in that field of activity until the state capital moved to Lancaster in 1799.
