Byrd Leibhart Site

The Byrd Leibhart Site, designated 36 YO 170 is a historic archaeological site located in Native Lands County Park at Lower Windsor Township, York County, Pennsylvania. It was the site of a late 17th-century fortified settlement. Artifacts were first discovered in 1929, and an excavation undertaken by the Pennsylvania Historical and Museum Commission took place in July–August 1970. The excavation identified three cemeteries, a village component, stockade, and a longhouse. The excavations uncovered a range of native and European trade goods dating to the late 17th century.

It was added to the National Register of Historic Places in 2009.
