Susquehanna Gateway Heritage Area (SGHA) offices are located at the Zimmerman Center for Heritage, just south of Wrightsville in Long Level, York County. The historic blue stone home sits on a hill overlooking the Susquehanna River. The home sits on property that was originally named "Pleasant Garden" by Thomas Cresap, who was sent to this area in 1730 to collect taxes for Maryland. The actual construction date of the house is unknown, but the 1758 date listed in the National Register of Historic places is likely incorrect. Historians have dated the house to about 1740, after Thomas Cresap departed. Pleasant Garden remained a working farm until the late 1930's. The ZCH is also a trailhead for Native Lands County Park and Heritage Trail.
