Northumberland, Pennsylvania

The Northumberland Historic District is a historic district listed in the US government's National Register of Historic Places in 1988. The "gem" of the district is a National Historic Landmark, the Joseph Priestley House. It includes one other separately Registered Historic Place, the Dr. Joseph Priestley House, also known as the "Priestley-Forsyth Memorial Library". It is bordered roughly by 4th Street, A Street, N. Shore Railroad, and Wheatley Avenue in Northumberland, Pennsylvania.In 1988 there were more than 100 contributing structures and 73 non-contributing structures in the district.

The Priestley-Forsyth Memorial Library, also known as the Dr. Joseph Priestley House or Cross Keys Inn, in Northumberland, Pennsylvania, was listed on the National Register of Historic Places in 1981.

The Joseph Priestley House was the American home of eighteenth-century British theologian, Dissenting clergyman, natural philosopher (and co-discoverer of oxygen), educator, and political theorist Joseph Priestley (1733–1804) from 1798 until his death. Located in Northumberland, Pennsylvania, the house, which was designed by Priestley's wife Mary, is Georgian with Federalist accents. The Pennsylvania Historical and Museum Commission (PHMC) operated it as a museum dedicated to Joseph Priestley from 1970 to August 2009, when it closed due to low visitation and budget cuts. The house reopened in October 2009, still owned by the PHMC but operated by the Friends of Joseph Priestley House (FJPH). Fleeing religious persecution and political turmoil in Britain, the Priestleys emigrated to the United States in 1794 seeking a peaceful life. Hoping to avoid the political troubles that had plagued them in Britain and the problems of urban life they saw in the United States, the Priestleys built a house in rural Pennsylvania. Nevertheless, political disputes and family troubles dogged Priestley during the last ten years of his life. After the Priestleys died, their home remained in private hands until the turn of the twentieth century, when George Gilbert Pond, a professor from what is now Pennsylvania State University, bought it and attempted to found the first Priestley museum. He died before he could complete the project and it was not until the 1960s that the house was first carefully restored by the PHMC and designated a National Historic Landmark. A second renovation was undertaken in the 1990s to return the home to the way it looked during Priestley's time. The home has been a frequent place of celebration for the American Chemical Society; they commemorated the centennial and bicentennial of the discovery of oxygen gas by Priestley as well as the 250th anniversary of Priestley's birth.

The West Branch Division of the Pennsylvania Canal ran 73 miles (117 km) from the canal basin at Northumberland, Pennsylvania, at the confluence of the West Branch Susquehanna River with the main stem of the Susquehanna River, north through Muncy, then west through Williamsport, Jersey Shore, and Lock Haven to its terminus in Farrandsville. At its southern terminus in the Northumberland basin, the West Branch Canal met the North Branch Canal and the Susquehanna Division Canal. Through these connections to other divisions of the Pennsylvania Canal, it formed part of a multi-state water transportation system including the Main Line of Public Works.Between Northumberland and Muncy, the canal lay east of the river. Beyond Muncy, where the river makes a right-angle turn, the canal lay to the north. Started in 1828 and completed in 1835, it had 19 lift locks overcoming a total vertical rise of about 140 feet (43 m). The locks, beginning with No. 13, slightly upstream of the Northumberland Canal Basin, and ending with No. 34 at Lockport, across the river from Lock Haven, included two guard locks and an outlet lock in addition to the 19 lift locks.The state intended to extend the West Branch Canal from Farrandsville further upstream along the West Branch Susquehanna River to the mouth of Sinnemahoning Creek. Plans called for 33 miles (53 km) of canal, but the project was abandoned along with the idea that the West Branch Canal would eventually connect to the Allegheny River in western Pennsylvania.

The West Branch Susquehanna River is one of the two principal branches, along with the North Branch, of the Susquehanna River in the Northeastern United States. The North Branch, which rises in upstate New York, is generally regarded as the extension of the main branch, with the shorter West Branch being its principal tributary. The West Branch, which is 243 miles (391 km) long, is entirely within the state of Pennsylvania, draining a large mountainous area within the Allegheny Plateau in the western part of the state. Along most of its course it meanders past mountain ridges and through water gaps, forming a large zigzag arc through central Pennsylvania around the north end of the Allegheny Mountains. In colonial times the river valley provided an important route to the Ohio River valley. In the 19th century, its lower valley became a significant industrial heartland of Pennsylvania. In the 20th century, the upper reaches of the West Branch turned a yellow/orange color due to sulfurous drainage from nearby and abandoned deep bituminous coal mines.

The newer part is the 54-acre (22 ha) marina on the southern end of Packer Island in Upper Augusta Township, Northumberland County. Packer's Island lies between the city of Sunbury and the borough of Northumberland at the confluence of the two branches of the river.

Fort Augusta was a stronghold in Northumberland County, Pennsylvania, in the upper Susquehanna Valley from the time of the French and Indian War to the close of the American Revolution. At the time, it was the largest British fort in Pennsylvania, with earthen walls more than two hundred feet long topped by wooden fortifications. With a garrison of over 300 troops and walls specially constructed to resist artillery, it presented a formidable defense and was never attacked. It served as a refuge for local settlers during the French and Indian War and during the American Revolutionary War. It was abandoned in 1780 and dismantled in 1796.
