Governor Road, commissioned by Sir William Keith in 1722, bisects the property. At the orginal entrance to the property, there are several features. The first is a three walled ruin, which is believed to be the remains of a barn dating to 1735-37. The second feature is a stone marker carved with '18 M to P’, which probably indicates 18 miles to Philadelphia from that point on Governor Rd. It may be an early mail delivery marker. Directly past the ramp to this barn are 2 stone gate posts which likely date from the same period.
