Clinton County Courthouse

Lock Haven is a city in and the county seat of Clinton County, in the U.S. state of Pennsylvania. Located near the confluence of the West Branch Susquehanna River and Bald Eagle Creek, it is the principal city of the Lock Haven Micropolitan Statistical Area, in a combined statistical area that includes Williamsport. Its population in 2010 was 9,772. Built on a site long favored by pre-Columbian peoples, Lock Haven began in 1833 as a timber town and a haven for loggers, boatmen, and other travelers on the river or the West Branch Canal. Resource extraction and efficient transportation financed much of the city's growth through the end of the 19th century. In the 20th century, a light-aircraft factory, a college, and a paper mill contributed to the economy. The city has three sites on the National Register of Historic Places: Memorial Park Site, a significant pre-Columbian archaeological find; Heisey House, a Victorian-era museum; and Water Street District (courthouse pictured), with a mix of 19th- and 20th-century architecture.
