Lock Haven, the county seat, is a city in Clinton County located in northern Pennsylvania 24 miles southwest of Williamsport. The Lock Haven University is located here. Established in 1833, the city's importance and name grew out of it's location along the West Branch Susquehanna River and the many canal 'locks' for the Pennsylvania and Bald Eagle Canals. The city was known as a 'haven' of rest for the raftsmen floating timber to sawmills. The Heisey Museum on Water Street is the place to visit to learn and see what life was like during the 1800's in Lock Haven. Lock Haven is also home to the Piper Aviation Museum that celebrates the history of William Piper and his Piper Cubs, known as the 'plane that taught the world to fly.' Today the 'Haven' is a small college town with an active downtown that welcomes visitors and their popular summer concerts on the river.
